I think my mistake is defining the parameter? I'm not sure how should be done

def square (number):
       return number * number
number = 
result = square (number)

1 Answer

there shouldn't be space between square and (number), indent your return statement so it is inline with the end of def and the number variable is not necessary since you declared it as a parameter so you code should look like:

def square(number):
    return number*number


def square(number):
    result = number*number
    return result
