Python Python Basics Functions and Looping Create a Function

I am having trouble understanding this question, mostly the part where it says "pass it the argument 3"

I'm not sure if "under the function" means inside or after the func ends.

squaring.py 
def square(number):
    return (number * number)
result = sqaure

When you call a function, you write its name followed by a pair of parentheses. If you also pass it an argument, you put that argument between the parentheses.

I totally agree with steve. Let me tell you in simple terms. We call a function with or without argument means if function asks for arguments we will pass it to the function it could be either string or it or float or dict or tuple or list anything. See below:

def square(num):
    return num*num

square(10)
square([1, 2, 3])

Only thing you need to remember is that when you call a function with arguments then its arguments should go in '()' and you always call a function outside of the the function or from the one function to another. See below:

def square(num):
    return num*num

def calling():
    result = square(5)
    print(result)

I hope this helps
