Question 2: Write a function that takes in a function cond and a number n and prints numbers from 1 to n where calling cond on that number returns True.

def keep_ints(cond, n):

"""Print out all integers 1..i..n where cond(i) is true

>>> def is_even(x):

... # Even numbers have remainder 0 when divided by 2.

... return x % 2 == 0

>>> keep_ints(is_even, 5)
