def make_keeper(n):
    """Returns a function which takes one parameter cond and prints
    out all integers 1..i..n where calling cond(i) returns True.
    >>> def is_even(x):
        # Even numbers have remainder 0 when divided by 2.
        return x % 2 == 0
    >>> make_keeper(5)(is_even)
    2
    4
    """
    def fun(cond):
        for i in range(1,n):
            if(cond(i)):
                print(i)
    return fun
Explanation:
- Define a function called fun that takes cond as input.
- loop from 1 to n and display the value if it meets the requirement.
