list_less_than_ten.py

'''
    Take a list, say for example this one:

    a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89]

    and write a program that prints out all the elements of the list 
    that are less than 5.

    Extras:

    1. Instead of printing the elements one by one, make a new list that 
       has all the elements less than 10 from this list in it and print out this new list.
    2. Write this in one line of Python.
    3. Ask the user for a number and return a list that contains only elements from the original list a that are smaller than that number given by the user.
