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 )

 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         en...
