How to correct an arithmetic error in python [duplicate]

Question

Hi, I am a relatively new programmer and my teacher gave us this problem to fix.

Thing is, I have no idea what to do because no matter what I do the code refuses to run.

def multiply(a, b):

  a * b

What is wrong with this problem?

Answer 1

You're on the right track. It is important to know that functions should return a value, so your code should look like this:

def multiply(a, b):

  return a * b

For something to happen once you run your code, afterward, you must call the function within a print statement and pass it some parameters. For example,

print(multiply(2,2))

Should output:

4
