Inspectopedia Help

Improper first parameter

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


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.


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.

Locating this inspection
