1)Program for Arithmetic Operations in Python

Task is to perform Arithmetic Operations in python

Below is the implementation:

#python program which performs simple arithmetic operations
# given two numbers
# given first number
numberone = 29
numbertwo = 13
# adding the  given two numbers
addnumb = numberone+numbertwo
# printing the result of sum of two numbers
print("Adding the given two numbers", numberone, "+", numbertwo, "=", addnumb)
# subtracting the given two numbers
diffnumb = numberone-numbertwo
# printing the result of difference of two numbers
print("Subtracting the given two numbers",
      numberone, "-", numbertwo, "=", diffnumb)
# multiply the given two numbers
mulnumb = numberone*numbertwo
# printing the result of product of two numbers
print("Multiplying the given two numbers",
      numberone, "*", numbertwo, "=", mulnumb)
# diving the given two numbers
divnumb = numberone+numbertwo
# printing the result of sum of two numbers
print("Dividing the given two numbers",
      numberone, "/", numbertwo, "=", divnumb)

Output:

Adding the given two numbers 29 + 13 = 42
Subtracting the given two numbers 29 - 13 = 16
Multiplying the given two numbers 29 * 13 = 377
Dividing the given two numbers 29 / 13 = 42

2)Program to Generate a Random Number

    # checking if the given number is negative number
    elif(given_Num < 0):
        print("The given number", given_Num, "is negative")
    # if the above conditions are not satisfied then the given number is zero
    else:
        print("The given number", given_Num, "is zero")


# given numbers
# given number 1
given_num1 = 169
# passing the given number to checkNumber Function which prints the type of number(+ve,-ve,0)
checkNumber(given_num1)
# given number 2
given_num1 = -374
# passing the given number to checkNumber Function which prints the type of number(+ve,-ve,0)
checkNumber(given_num1)

    # checking if the given number is even number
    if(given_Num % 2 == 0):
        print("The given number", given_Num, "is even number")
    # checking if the given number is odd number that is if given number is not even then it is odd number
    else:
        print("The given number", given_Num, "is odd number")


# given numbers
# given number 1

# given lower limit range
lower_range = 17
# given upper limit range
upper_range = 126
# initializing sum of range to 0
rangeSum = 0
# Using for loop to traverse from lower limit range to upper limit range
for i in range(lower_range, upper_range+1):
    rangeSum = rangeSum+i
print("the sum of all numbers between",
      lower_range, "to", upper_range, "=", rangeSum)

Output:

the sum of all numbers between 17 to 126 = 7865

ii)Using mathematical formula of sum of n natural numbers

sum of n natural numbers =( n * (n+1) ) /2

Below is the implementation:

# Python program to print the sum of all numbers in the given range
# given lower limit range
lower_range = 17
# given upper limit range
upper_range = 126
low_range = lower_range-1
# calculating the sum of natural numbers from 1 to lower limit range
lowSum = (low_range*(low_range+1))/2
# calculating the sum of natural numbers from 1 to upper limit range
highSum = (upper_range*(upper_range+1))/2
# calculating the sum of all numbers between the given range
rangeSum = highSum-lowSum
# printing the sum of all natural numbers between the given range
print("the sum of all numbers between",
      lower_range, "to", upper_range, "=", int(rangeSum))

Output:

the sum of all numbers between 17 to 126 = 7865

# Python program to print the even numbers in
#  given range(lower limit range and upper limit range)
# given lower limit range
lower_range = 17
# given upper limit range
upper_range = 126
# printing the even numbers in the giveen range using looop
# Iterate from lowe limit range to upper limit range
for numb in range(lower_range, upper_range+1):
    # checking if the number is divisible by 2
    if(numb % 2 == 0):
        # we will print the number if the number is divisible by 2

# Python program to split the given number into list of digits
# given number
numb = 123883291231775637829
# converting the given number to string
strnu = str(numb)
# splitting the given number into list of digits using map and list functions
listDigits = list(map(int, strnu))
# print the list of digits of given number
print(listDigits)

Output:

[1, 2, 3, 8, 8, 3, 2, 9, 1, 2, 3, 1, 7, 7, 5, 6, 3, 7, 8, 2, 9]

31)Python program to split the given string into list of characters

We will use the list() function to split the given string into list of characters

Below is the implementation:

# Python program to split the given string into list of characters
# given string
string = "HellothisisBtechGeeks"
# splitting the string into list of characters
splitstring = list(string)
# print the list of characters of the given string
print(splitstring)

Output:

['H', 'e', 'l', 'l', 'o', 't', 'h', 'i', 's', 'i', 's', 'B', 't', 'e', 'c', 'h', 'G', 'e', 'e', 'k', 's']

Here the string is converted into a list of characters.
