Python

Strings in Python:

True pangram: A Python string is an ordered collection of characters used to express and store text-based data. Strings are saved in an adjacent memory area as individual characters. It is accessible in both directions: forward and backward. Characters are merely symbols. Strings are immutable Data Types in Python, which means they cannot be modified once they are formed. Python check if string is all characters, Python check if string is latin, Python check if a string is all digits, Python check if string is a dictionary, It depends on function too whether pangram program in python without function or if not.

Pangram:

If a sentence or string contains all 26 letters of the English alphabet at least once, it is considered to be a pangram. There are some solutions for pangram (pangram hackerrank solution in python) are also considered.

Examples:

Example1:

Input:

given string ="Helloabcdfegjilknmporqstvuxwzy"

Output:

The given string helloabcdfegjilknmporqstvuxwzy is a pangram

Example2:

Input:

given string ="hellothisisbtechgeeks"

Output:

The given string hellothisisbtechgeeks is not a pangram

Python Program to Check if a String is a Pangram or Not

There are several ways to check if the given string is pangram or not some of them are:

Follow to check pangram python code

• Naive Approach
• Using set() method
• Using Counter() function (Hashing)

Drive into Python Programming Examples and explore more instances related to python concepts so that you can become proficient in generating programs in Python Programming Language.

Method #1:Naive Approach

Approach:

• Scan the given string or provide static input.
• Use the lower() method to convert this string to lowercase.
• The brute force method is to take a string that contains all of the letters of the English alphabet.
• Traverse through all of the alphabet’s characters string
• Check to see if this character appears in the given string.
• If it isn’t present, return False.
• Return True at the end of the loop (which implies it is pangram)

Below is the implementation:

# Python Program to Check if a String is a Pangram or Not
def checkPangramString(string):

    # creating a new string (alphabet string which stores all the alphabets of the english language
    AlphabetString = 'abcdefghijklmnopqrstuvwxyz'

    # Traverse through the alphabets string
    for char in AlphabetString:
        # Check if this character is present in given string .
        if char not in string.lower():
            # if yes then this character is not available hence return False
            return False
    # After the end of loop return True (which implies it is pangram)
    return True


# given string
string = "Helloabcdfegjilknmporqstvuxwzy"
# converting the given string into lower case
string = string.lower()
# passing this string to checkPangramString function which returns true
# if the given string is pangram else it will return false

if checkPangramString(string):
    print("The given string", string, "is a pangram")
else:
    print("The given string", string, "is not a pangram")

Output:

The given string helloabcdfegjilknmporqstvuxwzy is a pangram

Method #2:Using set() method

The following program can be easily implemented in Python by using the set() method.

Approach:

• Scan the given string or provide static input.
• Use the lower() method to convert this string to lowercase.
• Use the set() function to convert this string to a set.
• Determine the length of the set.
• If the length is 26, it is a pangram (since the English language has only 26 alphabets).
• Otherwise, it is not a pangram.

Below is the implementation:

# Python Program to Check if a String is a Pangram or Not
def checkPangramString(string):

    # converting given string to set using set() function
    setString = set(string)
    # calculate the length of the set
    length = len(setString)
    # If the length is 26, it is a pangram so return true
    if(length == 26):
        return True
    else:
        return False


# given string
string = "Helloabcdfegjilknmporqstvuxwzy"
# converting the given string into lower case
string = string.lower()
# passing this string to checkPangramString function which returns true
# if the given string is pangram else it will return false

if checkPangramString(string):
    print("The given string", string, "is a pangram")
else:
    print("The given string", string, "is not a pangram")

Output:

The given string helloabcdfegjilknmporqstvuxwzy is a pangram

Note:

This method is only applicable if the given string contains alphabets.

Method #3:Using Counter() function (Hashing)

The following program can be easily implemented in Python by using the counter() function

Approach:

• Scan the given string or provide static input.
• Use the lower() method to convert this string to lowercase.
• Calculate the frequency of all characters in the given string using Counter() method
• Calculate the length of the Counter dictionary.
• If the length is 26, it is a pangram (since the English language has only 26 alphabets).
• Otherwise, it is not a pangram.

Below is the implementation:

# Python Program to Check if a String is a Pangram or Not
# importing counter from collections
from collections import Counter


def checkPangramString(string):

    # Calculate the frequency of all characters in the given string
    # using Counter() method
    frequ = Counter(string)
    # calculate the length of the frequency dictionary which is
    # returned from counter() function
    length = len(frequ)
    # If the length is 26, it is a pangram so return true
    if(length == 26):
        return True
    else:
        return False


# given string
string = "Helloabcdfegjilknmporqstvuxwzy"
# converting the given string into lower case
string = string.lower()
# passing this string to checkPangramString function which returns true
# if the given string is pangram else it will return false

if checkPangramString(string):
    print("The given string", string, "is a pangram")
else:
    print("The given string", string, "is not a pangram")

Output:

The given string helloabcdfegjilknmporqstvuxwzy is a pangram

Note:

This method is only applicable if the given string contains alphabets.

Program to Compute a Polynomial Equation given that the Coefficients of the Polynomial are stored in a List

There are several ways to compute the value of the polynomial equation with given x from the given Coefficients in Python some of them are:

• Using for and while loop(User Input)
• Using for and while loop(Static Input)

Method #1:Using for and while loop(User Input)

Approach:

• Import the math module.
• Take a empty list.
• Loop from 1 to 4 using for loop as there are 4 coefficients terms in the equation.
• Scan the coefficient as user input using int(input()) function.
• Add this to the list using append() function.
• Scan the value of x as user input using int(input()) function.
• To compute the value of the polynomial expression for the first three terms, use a for loop and a while loop and store it in a sum variable.
• To the total variable, add the fourth term.
• The computed value should be printed.
• Exit of program.

Below is the implementation:

import math
# Take a empty list.
coefflist = []
# Loop from 1 to 4 using for loop as there are 4 coefficients terms in the equation.
for t in range(4):
    # Scan the coefficient as user input using int(input()) function.
    elemen = int(input('Enter some random coefficient ='))
    # Add this to the list using append() function.
    coefflist.append(elemen)
# Scan the value of x as user input using int(input()) function.
x = int(input('Enter some random value of x ='))
# Taking a variable which stores totalValue and initialize it with 0
totalValue = 0
temp = 3
for k in range(0, 3):
    while(temp > 0):
        totalValue = totalValue+(coefflist[k]*(x**temp))
        # breaking the while looop
        break
    temp = temp-1
# To the total variable, add the fourth term.
totalValue = totalValue+coefflist[3]
print("The total value of the given polynomial " +
      str(coefflist[0])+' x^3 +'+str(coefflist[1])+' x^2 +'+str(coefflist[2])+' x +' +
      str(coefflist[3]), 'with the given value of x=', x, 'is', totalValue)

Output:

Enter some random coefficient =1
Enter some random coefficient =9
Enter some random coefficient =3
Enter some random coefficient =5
Enter some random value of x =8
The total value of the given polynomial 1 x^3 +9 x^2 +3 x +5 with the given value of x= 8 is 1117

Explanation:

• The math module has been imported.
• The user must enter the polynomial coefficients, which are saved in a list.
• In addition, the user must input the value of x.
• The for loop, which is used to retrieve the coefficients in the list, changes the value of I from 0 to 2.
• The power for the value of x is determined by the value of j, which varies from 3 to 1.
• This method is used to compute the values of the first three terms.
• The final term is added to the total.
• The final calculated value is printed.

Method #2: Using for and while loop(Static Input)

Approach:

• Import the math module.
• Take in the polynomial equation coefficients as static input in given list.
• Give the value of x as static input.
• To compute the value of the polynomial expression for the first three terms, use a for loop and a while loop and store it in a sum variable.
• To the total variable, add the fourth term.
• The computed value should be printed.
• Exit of program.

Below is the implementation:

import math
# Take in the polynomial equation coefficients as static input in given list.
coefflist = [7, 1, 3, 2]
# Give the value of x as static input.
x = 5
# Taking a variable which stores totalValue and initialize it with 0
totalValue = 0
temp = 3
for k in range(0, 3):
    while(temp > 0):
        totalValue = totalValue+(coefflist[k]*(x**temp))
        # breaking the while looop
        break
    temp = temp-1
# To the total variable, add the fourth term.
totalValue = totalValue+coefflist[3]
print("The total value of the given polynomial " +
      str(coefflist[0])+' x^3 +'+str(coefflist[1])+' x^2 +'+str(coefflist[2])+' x +' +
      str(coefflist[3]), 'with the given value of x=', x, 'is', totalValue)

Output:

The total value of the given polynomial 7 x^3 +1 x^2 +3 x +2 with the given value of x=5 is 917

Explanation:

• The for loop, which is used to retrieve the coefficients in the list, changes the value of I from 0 to 2.
• The power for the value of x is determined by the value of j, which varies from 3 to 1.
• This method is used to compute the values of the first three terms.
• The final term is added to the total.

Age in days: In the previous article, we have discussed Python Program to Check Strontio Number or Not.
Given the Date of Birth and task is to calculate the corresponding age in days. Python code to show age in years, months days, Python age in days, Python code for date of birth, Python age calculator date time, If you carefully observe in the content you will get it.

datetime module:

Your age in days: The datetime module contains numerous classes that can be used to manipulate date and time in both simple and complex ways.

In this, the date is formatted as the year month date (YY, MM, DD).

datetime.today() :The current date/system date is returned by datetime.today().

To calculate age from date of birth, subtract the date of birth from the current date.

timedelta() function in Python:

The Python timedelta() function is part of the datetime library and is commonly used for calculating date differences. It can also be used for date manipulation in Python. It is one of the simplest methods for manipulating dates.

Python make list of odd numbers: In the previous article, we have discussed Python Program to Check Armstrong Number using Recursion

Given a list and the task is to find the sum of odd numbers using recursion in a given list in python.

Recursion:

Recursion is the process by which a function calls itself directly or indirectly, and the associated function is known as a recursive function. Certain issues can be addressed fairly easily using a recursive approach. Towers of Hanoi (TOH), Inorder /Preorder/Postorder Tree Traversals, DFS of Graph, and other analogous issues are examples.

Some of them are:

• Sum of array using recursion in python
• Sum of array elements using recursion in c
• Sum of array using recursion coding ninjas
• Sum of array elements using recursion javascript

Examples:

Example1:

Input:

Given List = [6, 12, 4, 2, 3, 9, 1, 5]

Output:

The Sum of Odd Elements in a given list [6, 12, 4, 2, 3, 9, 1, 5] = 18

Example2:

Input:

Given List = [4, 3, 1, 5, 11]

Output:

The Sum of Odd Elements in a given list [4, 3, 1, 5, 11] = 20

Below are the ways to find the sum of odd numbers using recursion in a given list in python:

• Using Recursion (Static Input)
• Using Recursion (User Input)

Method #1: Using Recursion (Static Input)

Approach:

• Give the list as static input and store it in a variable.
• Calculate the length of the given list and store it in another variable.
• Take a variable say rslt_sum and initialize its value to 0.
• Pass the given list and length of the given list as the arguments to the oddelemt_sum function.
• Create a recursive function to say oddelemt_sum which takes the given list and length of the given list as the arguments and returns the sum of odd numbers in a given list using recursion.
• Make the rslt_sum a global declaration.
• Check if the length of the given list is greater than 0 using the if conditional statement.
• If the statement is true, then subtract 1 from the length of the given list and store it in a variable k.
• Check if the element present at the index k of the given list is odd using the modulus operator and if conditional statement.
• If the statement is true, add the element present at the index k of the given list to the above-initialized rslt_sum.
• Store it in the same variable.
• Pass the given list and k value as the arguments to the oddelemt_sum function.{Recursive Logic}
• Return rslt_sum.
• Print the sum of odd numbers in the above-given list.
• The Exit of the Program.

Below is the implementation:

# Create a recursive function to say oddelemt_sum which takes the given list and length
# of the given list as the arguments and returns the sum of odd numbers in a given list
# using recursion.


def oddelemt_sum(gven_lst, len_lst):

# Store it in a variable.
gven_lst = list(map(int, input(
   'Enter some random List Elements separated by spaces = ').split()))
# Calculate the length of the given list and store it in another variable.
len_lst = len(gven_lst)

Program to Count Non-Palindrome words in a Sentence

Below are the ways to count all the Non-palindromic words in a given sentence.

• Using For Loop (Static Input)
• Using For loop (User Input)

Method #1: Using For Loop (Static Input)

Approach:

• Give the string as static input and store it in a variable.
• Take an empty list say “lst” and store it in another variable.
• Split the given string using the split() function and store it in another variable.
• Loop in the above-obtained split list of words using the for loop.
• Check if the iterator value is not equal to the reverse of the iterator value using the if conditional statement.
• If the statement is true, then append the respective iterator value to the above initialized empty list using the append() method.
• Calculate the length above initialized list “lst” using the len() function and store it in a variable.
• Print the count of all the Non-palindromic words in a given sentence.
• The Exit of the Program.

Below is the implementation:

# Give the string as static input and store it in a variable.
gvn_str = "dad and mom both ordered to bring sos in malayalam"
# Take an empty list and store it in another variable.
lst = []
# Split the given string using the split() function and store it in another variable.
splt_str = gvn_str.split()
# Loop in the above-obtained split list of words using the for loop.
for wrd in splt_str:
    # Check if the iterator value is not equal to the reverse of the iterator value using
    # the if conditional statement.
    if wrd != wrd[::-1]:
     # If the statement is true, then append the respective iterator value to the
        # above initialized empty list using the append() method.
        lst.append(wrd)
# Calculate the length above initialized list "lst" using the len() function
# and store it in a variable.
# Print the count of all the Non-palindromic words in a given sentence.
count = len(lst)
# Print the count of all the Non-palindromic words in a given sentence.
print("The count of all the Non-palindromic words in a given sentence =", count)

Output:

The count of all the Non-palindromic words in a given sentence = 6

Method #2: Using For loop (User Input)

Approach:

• Give the string as user input using the input() function and store it in a variable.
• Take an empty list say “lst” and store it in another variable.
• Split the given string using the split() function and store it in another variable.
• Loop in the above-obtained split list of words using the for loop.
• Check if the iterator value is not equal to the reverse of the iterator value using the if conditional statement.
• If the statement is true, then append the respective iterator value to the above initialized empty list using the append() method.
• Calculate the length above initialized list “lst” using the len() function and store it in a variable.
• Print the count of all the Non-palindromic words in a given sentence.
• The Exit of the Program.

Below is the implementation:

# Give the string as user input using the input() function and store it in a variable.
gvn_str = input("Enter some random string = ")
# Take an empty list and store it in another variable.
lst = []
# Split the given string using the split() function and store it in another variable.
splt_str = gvn_str.split()
# Loop in the above-obtained split list of words using the for loop.
for wrd in splt_str:
    # Check if the iterator value is notequal to the reverse of the iterator value using
    # the if conditional statement.
    if wrd != wrd[::-1]:
     # If the statement is true, then append the respective iterator value to the
        # above initialized empty list using the append() method.
        lst.append(wrd)
# Calculate the length above initialized list "lst" using the len() function
# and store it in a variable.
# Print the count of all the Non-palindromic words in a given sentence.
count = len(lst)
# Print the count of all the Non-palindromic words in a given sentence.
print("The count of all the Non-palindromic words in a given sentence =", count)

Output:

Enter some random string = My mom and dad treats me in equal level

Input:

Given list =[23, 11, 1, 7, 8, 6, 3]

Output:

The leaders of the given list [23, 11, 1, 7, 8, 6, 3] are :
23
11
8
6
3

Example2:

Input:

Given List =  [1, 2, 3, 7, 8, 6]

Program to Find Leaders in an Array/List in Python

Below are the ways to find all the leaders of the given list in python some of them are:

• Using For Loop (Static Input)
• Using For loop (User Input)

Method #1: Using For Loop (Static Input)

Approach:

• Give the list as static input and store it in a variable.
• Calculate the length of the list and store it in another variable.
• Loop from 0 to the length of the list using the For loop.
• Loop from parent loop iterator value to the length of the list using another Nested for loop(Inner For loop)
• Check if the element at the index of the parent loop iterator value is less than or equal to the element at the index of the inner loop iterator value.(gvnlist [ m ] <= gvnlist [ n ] ) using the if conditional statement.
• If it is true then break the inner loop using the break keyword.
• After the end of the inner For loop check if the inner loop iterator value is equal to the length of the given list -1 using the if conditional statement.
• If it is true then it is the leader so print it.
• The Exit of the Program.

Below is the implementation:

# Give the list as static input and store it in a variable.
gvnlstt = [23, 11, 1, 7, 8, 6, 3]
# Calculate the length of the list and store it in another variable.
lstleng = len(gvnlstt)
print('The leaders of the given list', gvnlstt, 'are :')
# Loop from 0 to the length of the list using the For loop.
for m in range(lstleng):
    # Loop from parent loop iterator value to the length of the list
    # using another Nested for loop(Inner For loop)
    for n in range(m+1, lstleng):
            # Check if the element at the index of the parent loop iterator value
        # is less than or equal to the element at the index of the inner loop iterator value.
        # (gvnlist[m] <= gvnlist[n]) using the if conditional statement.
        if (gvnlstt[m] <= gvnlstt[n]):
            # If it is true then break the inner loop using the break keyword.
            break

            # After the end of the inner For loop check if the inner loop iterator value
        # is equal to the length of the given list - 1 using the if conditional statement.
    if(n == lstleng-1):
        # If it is true then it is the leader so print it.
        print(gvnlstt[m])

Output:

The leaders of the given list [23, 11, 1, 7, 8, 6, 3] are :
23
