Question about function calls

[Afif Khaja]

Hi, 

I would like to know how I can fix this sample code:

def quicksort(a):

    print a^2

def sortTime(function):

    if (function == quicksort):

        print function(5)

sortTime(quicksort)

# Should have output of 5 ^ 2 = 25 but instead the output is:

# >>>

# 7

# None

# >>>

Thanks,

Afif Khaja

A long time ago in a galaxy far far away, we learned that ^ is not used for exponentiation, but **. The caret operator is used for something a bit more mysterious (a bitwise arithmetic operation called "xor"). 

You're seeing "None" because you're printing the result of a function which has no return statement.
