Use the Rename refactoring to change names of symbols, files, and all the references to them throughout code.
Renaming local variables or private methods can be done easily inline since only the limited scope is affected. Renaming classes or public methods could potentially impact a lot of files. Preview potential changes before you refactor.
Rename code in place
In the editor start renaming a code element. PyCharm will display in the gutter.
Click the gutter icon or press Alt+Enter and apply a suggestion.
You might be prompted to confirm changes in comments.
Once you confirm your choice, PyCharm renames the code element and updates its usages accordingly.
In the editor, select an element you want to rename. If you need to rename a file, select one in the Project tool window.
Press Shift+F6 or from the main menu, select.
You can specify additional options. For example, specify where to search for element occurrences, or what else to rename. You can also specify a scope for the refactoring.
Click Preview to see the potential changes or click Refactor.
When you click Preview, PyCharm opens the Find tool window with the results of found usages where you can check the results and confirm the refactoring (Do Refactor).
Next time you invoke the Rename refactoring, PyCharm remembers the options you have specified inside the Rename dialog.
Let's rename a method:
import datetime def was_published_today(self): return self.pub_date.date () == datetime.date.today()
import datetime def published_today(self): return self.pub_date.date () == datetime.date.today()
