Squaring.py Challenge

How do I call a new function and pass it a new variable? I am on part two of the challenge and I created a function that squares a number entered.

squaring.py 
def square(number):
    return(number * number)

To call a function with an argument, just put the argument between the parens. e.x.:

def square(number):
    return number * number

# The below line calls the function "square", but it doesn't do anything with
# the returned value:
square(3)

If you merely call square, however, it will only return the value 3. What happens to 3? Well, it isn't being used, or stored within a variable, so it's kind of just floating in space. To assign it to a variable, you could write this:

result = square(3)

I hope this helps! :grin:
