- Write a function to check the input value is Armstrong and also write the function for Palindrome.
- Write a recursive function to print the factorial for a given number.
- Write a function that takes a character (i.e. a string of length 1) and returns True if it is a vowel, False otherwise.
- Define a function that computes the length of a given list or string.
- Write a program that takes two lists and returns True if they have at least one common member.

age. Print out a message addressed to them that tells them the year that they
will turn 100 years old.

= input('Enter your name? \n')
age
= int(input('How old are you? \n'))
hundred
= int((100-age) + datetime.now().year)
