'''

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:

- Instead of printing the elements one by one,

make a new list that has all the elements less than 5 from this list in it and print out this new list.

- Write this in one line of Python.

- Ask the user for a number and return a list that contains only elements from the original list that are smaller than the number given by the user.

print('Those are numbers in the group smaller than 5: ')

for number in number_list:

if number < 5:
