Getting syntax errorin my program

[dock1926]

I'm getting a syntax error in my program and I can't seem to get it fixed. It could be a simple indent issue but I have tried that. I am a newbie so it is probably something simple I've been racking my brain with this any help would be appreciated.

#Mylib

class calculatorClass:

return a + b

def divide(self,a, b):
try:
return a / b
# This exception will be raised when the user attempts division by zero
# Implemented here so if the users input is '0' it will display error that you can't divide by zero

There is literally no indentation in your MyLib module.
