Write a python program to find factorial of a number ?

Factorial 

When we recursively multiply number incrementing from 1 to a given number then its called factorial of that number. We use the notation ! to denote factorial. 

Factorial of 5 = 5! = 5X4X3X2X1

Code

def findFactorial(num):

    try:

        a = int(num)

        value = a

        while a>1:            

            a = a-1

            value = value*a

            print(value)

        print("Factorial of {} is {}".format(num,value))

    except:

        print("You have not entered a number")

number = input("enter a number")

findFactorial(number)

Write a python program to check if a number is palindrome ?

 Palindrome

Definition of palindrome is any number/string which is same after getting reversed is palindrome.

Example - 123321, 131, GAG, EYE etc

Below is the python code to check if a string or number is palindrome

CODE

def check_palindrome(input_value):

    is_pallindrome = False

    letters_of_input = list(input_value)

    string_size = len(letters_of_input)

    start_index = 0

    end_index = string_size - 1

    mid_index = int(string_size/2) - 1

    while start_index <= mid_index:

        if input_value[start_index] == input_value[end_index]:

            is_pallindrome = True

        else:

            is_pallindrome = False

            break

        start_index = start_index+1

        end_index =end_index-1

        print(input_value[start_index],input_value[end_index])

    return is_pallindrome

input_data = input("Enter a number/string to check if its palindrome: ")

if check_palindrome(input_data) == True:

    print("The input value {} is palindrome".format(input_data))

else:

    print("The input value {} is not palindrome".format(input_data))
