In the previous article, we have discussed Python Program to Calculate the Area of a Trapezoid
Buzz Number:

If a number ends in 7 or is divisible by 7, it is referred to as a Buzz Number.

some of the examples of Buzz numbers are 14, 42, 97,107, 147, etc

The number 42 is a Buzz number because it is divisible by ‘7’.
Because it ends with a 7, the number 107 is a Buzz number.

Given a number, the task is to check whether the given number is Buzz Number or not.

• Write a Java Program to Check Buzz Number
• Python Program to Check a Binary Number is Divisible by a Number N
• Python Program to Find the Smallest Divisor of an Integer

Examples:

Example1:

Input:

Given number = 97

Output:

The given number { 97 } is a Buzz Number

Example2:

Input:

Given number = 120

Output:

The given number { 120 } is not a Buzz Number

Program to Check Buzz Number or Not

Below are the ways to check whether the given number is Buzz Number or not.

• Using modulus operator (Static input)
• Using modulus operator (User input)

Method #1: Using modulus operator (Static input)

Approach:

• Give the number as static input and store it in a variable.
• Check if the given number modulus ‘7’ is equal to ‘0’ or if the given number modulus ’10’ is equal to ‘7’ or not using if conditional statement.
• If the above statement is True, then print “The given number is a Buzz Number”.
• Else if the statement is False, print “The given number is Not a Buzz Number”.
• The Exit of the program.

Below is the implementation:

# Give the number as static input and store it in a variable.
gvn_numbr = 14
# Check if the given number modulus '7' is equal to '0' or if the given number modulus '10'
# is  equal to '7' or not using if  conditional statement.
if gvn_numbr % 7 == 0 or gvn_numbr % 10 == 7:
 # If the above statement is True ,then print "The given number is a Buzz Number".
    print("The given number {", gvn_numbr, "} is a Buzz Number")
else:
  # Else if the statement is False, print "The given number is Not a Buzz Number" .
    print("The given number {", gvn_numbr, "} is not a Buzz Number")

Output:

The given number { 14 } is a Buzz Number

Here the number 14 is a Buzz Number.

Method #2: Using modulus operator (User input)

Approach:

• Give the number as user input using int(input()) and store it in a variable.
• Check if the given number modulus ‘7’ is equal to ‘0’ or if the given number modulus ’10’ is equal to ‘7’ or not using if conditional statement.
• If the above statement is True, then print “The given number is a Buzz Number”.
• Else if the statement is False, print “The given number is Not a Buzz Number”.
• The Exit of the program.

Below is the implementation:

# Give the number as user input using int(input()) and store it in a variable.
gvn_numbr = int(input("Enter some random number = "))
# Check if the given number modulus '7' is equal to '0' or if the given number modulus '10'
# is  equal to '7' or not using if  conditional statement.
if gvn_numbr % 7 == 0 or gvn_numbr % 10 == 7:
 # If the above statement is True ,then print "The given number is a Buzz Number".
    print("The given number {", gvn_numbr, "} is a Buzz Number")
else:
  # Else if the statement is False, print "The given number is Not a Buzz Number" .
    print("The given number {", gvn_numbr, "} is not a Buzz Number")

Output:

Enter some random number = 49
The given number { 49 } is a Buzz Number

In the previous article, we have discussed Python Program to Extract Only Characters from a Given String
Given two strings, the task is to find the common characters between Two Strings.

In this case, we use some of the built-in functions like join(), lower(), sorted() and intersection() methods.

join() :

The string method join()  takes all of the items in an iterable and returns a string after joining them all together. Iterable types include list, tuple, string, dictionary, and set.

lower() :

As the name indicates, It takes a string and converts all uppercase characters to lowercase before returning it.

sorted method() :

The sorted() method is used to orderly sort the elements of a sequence (either ascending or descending).

intersection() method :

The intersection() method is used to find all the elements that are shared by two given sets.

• Python Program to Group Words with the Same Set of Characters
• Python Program to Sort digits of a Number in Ascending Order
• Python Program to Find All Non Repeated Characters in a String

Examples:

Example 1:

Given First String = Hello Btechgeeks
Given Second String = good morning

Output:

The Common Characters between the above given two Strings =   go

Definition of Keyword:–

A keyword is a reserved word in programming languages that has its own unique meaning. It conveys their unique meaning to the interpreter while executing. And, when using variables in code, we never use the keyword as the variable name.

Some of the keywords in Python are :

True, False, finally, not, or, and, if, else, elif, None, lambda, nonlocal, not, except, as, pass, try, def, in, with, while, import, continue, from, raise, return, global, class, break, from, assert, for, in, with, is, yield, del, and so on.

kwlist method:

To accomplish this, we must import a built-in Python module called “keyword,” and within the keyword module, there is a method called “kwlist” that stores all of the keywords found in the Python language in a list. And if the given string appears in the list, it is considered a keyword; otherwise, it is not a keyword.

• In Python, How to Read a JSON File?
• Python Program to Find the Next Armstrong Number
• Python Program to Break a List into Chunks of Size N

Examples:

Example1:

Input:

Given First String = btechgeeks
Given Second String = for

Output:

The given string{ btechgeeks } is not a keyword
The given string{ for } is a keyword

Example 2:

Input:

Given First String = while
Given Second String = for

Output:

The given string{ while } is a keyword
The given string{ for } is a keyword

In the previous article, we have discussed Python Program to Find Super Factorial of a Number.
Math Module :

Python’s math module is a built-in module. By importing this module, we can perform mathematical computations.

Numerous mathematical operations like ceil( ),floor( ),factorial( ),mod( ),value of pi ,…..etc .can be computed with the help of math module.

math.sin() function:

To compute the sine value, we must use the sine function as math. sine() takes only one parameter, the degree value.

Sin is a trigonometric function that represents the Sine function. Its value can be calculated by dividing the length of the opposite side by the length of the hypotenuse of a right-angled triangle, as we learned in math.

By importing the math module that contains the definition, we will be able to use the sin() function in Python to obtain the sine value for any given angle.

Armstrong Number:

Beginners sometimes ask what the Armstrong number, also known as the narcissist number, is. Because of the way the number behaves in a given number base, it is particularly interesting to new programmers and those learning a new programming language. The Armstrong number meaning in numerical number theory is the number in any given number base that forms the sum of the same number when each of its digits is raised to the power of the number’s digits.

Ex: 153, 371 etc.

Explanation:

Here 1^3 + 5^3 + 3^3 = 153  so it is Armstrong Number

Example1:

Input:

Given lower limit =  50
Given upper limit =  1800

Output:

The Armstrong numbers in the given range: 
153
370
371
407
1634

Estimated Monthly Installment (EMI):

EMI is an abbreviation for Estimated Monthly Installment. It is a set amount of money paid by the customer or borrower to the bank or lender on a set date each month of the year. This amount is deducted from the customer’s or borrower’s account every month for a set number of years until the loan is fully paid off by the customer or borrower to the bank or lender.

Formula :

EMI = (P*R*(1+R)^T)/((1+R)^T-1)

where P = Principle

T = Time

R = Rate of interest.

Given principle, Rate, Time, and the task are to calculate EMI for the given input values in Python
