# Title: List Comprehensions

# Let’s say I give you a list saved in a variable: 
# a = [1, 4, 9, 16, 25, 36, 49, 64, 81, 100]. 
# Write one line of Python that takes this list a and makes 
# a new list that has only the even elements of this list in it.

def evens(list):
    return [x for x in list if x % 2 == 0]

print(evens([1, 4, 9, 16, 25, 36, 49, 64, 81, 100]))
