PyCharm 4.0.0 Web Help

The Push Members Down refactoring helps clean up the class hierarchy by moving class members to a subclass. The members are then relocated into the direct subclasses only.

Example

Before After
class SuperClass:
    def super_method(self):
        pass

class SubClassOne(SuperClass):
    def my_method(self):
        pass

class SubClassTwo(SuperClass):
    def my_method(self):
        pass
class SuperClass:
    pass

class SubClassOne(SuperClass):
    def my_method(self):
        pass

    def super_method(self):
        pass

class SubClassTwo(SuperClass):
    def my_method(self):
        pass

    def super_method(self):
        pass
To push members down
  1. In the editor open a class, whose members you need to push down.
  2. On the main menu, or on the context menu of the editor tab, choose Refactor | Push Members Down. Push Members Down dialog box displays the list of members to be pushed down.
  3. In the Members to be pushed down area, select the members you want to move. Note that the member at caret is already selected.

    If pushing a member might cause problems, you will be notified with red highlighting. It means that, if the situation is unattended, an error will emerge after refactoring. PyCharm prompts you with a Problems Detected dialog, where you can opt to ignore or fix the problem.

  4. Preview and apply changes.
