Improper first parameter

Reports methods that lack the first parameter that is usually named self.

Example:

class Movie:

   def show():
       pass

When the quick-fix is applied, the code changes to:

class Movie:

   def show(self):
       pass

The inspection also reports naming issues in class methods.

Example:

class Movie:
    @classmethod
    def show(abc):
        pass

Since the first parameter of a class method should be cls, the IDE provides a quick-fix to rename it.
