pylint, probably:

PS C:\Users\Peter> type demo.py
class Stuff:
     def __init__(self):
         self.x = 0
     def update(self):
         self.y = 0
PS C:\Users\Petery> pylint demo.py
************* Module demo
...
demo.py:5:8: W0201: Attribute 'y' defined outside __init__ 
(attribute-defined-outside-init)
...

Your code has been rated at -4.00/10
