Why does pycharm propose to change method to static

Question

The new pycharm release (3.1.3 community edition) proposes to convert the methods that don\'t work with the current object\'s state to static.

Answer 1

This error message just helped me a bunch, as I hadn't realized that I'd accidentally written my function using my testing example player

my_player.attributes[item] 

instead of the correct way

self.attributes[item]
