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.

It might be a bit messy, but sometimes you just don't need to access self, but you would prefer to keep the method in the class and not make it static. Or you just want to avoid adding a bunch of unsightly decorators. Here are some potential workarounds for that situation.

If your method only has side effects and you don't care about what it returns:

def bar(self):
    doing_something_without_self()
    return self

If you do need the return value:

def bar(self):
    result = doing_something_without_self()
    if self:
        return result

Now your method is using self, and the warning goes away!
