Python Python Basics Functions and Looping Create a Function

I don't understand. Please help.

I tried but cannot resolve this problem.

def square(number):
    square_of_the_value_passed_in = "number"
    return square_of_the_value_passed_in

Here's one way to tackle the challenge...

  • First, you need to define the function. You've already did that correctly
  • Then, you need to square the number passed in and save it in a variable. To square a variable, you simply multiply it by itself, e.g. number * number
  • Return the variable

You defined the function properly but there is no need for your second line of code. Just think of how to square a number (just multiply it by itself) and then return that.

Remember, you're squaring the parameter (number) so you will just be returning (number * number) in this exercise
