Use the Rename refactoring to change names of symbols, files, variables, functions, packages, modules and all the references to them throughout code.
Renaming local variables or functions can be done easily inline since only the limited scope is affected. Renaming classes or their methods could potentially impact a lot of files. Preview potential changes before you refactor.

Use a quick-fix or a gutter icon
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.
PyCharm renames the code element and updates its usages accordingly.
Rename a directory or a module

From the context menu, select(Shift+F6).
In the Rename dialog that opens, type the new name, specify additional options and the scope of the refactoring, and click Refactor.

You can perform the rename refactoring inline or press Shift+F6 again to open the Rename dialog. Enter a new name of the element to enable the Preview and Refactor buttons.

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).
