How can I bulk rename variables in PyCharm?

In PyCharm, you can use the “Refactor” feature to change variable names in bulk. Here are the specific steps:

1. Select the variable name you want to modify, hold down the “Shift” key and click on the variable name, or use the mouse to drag and select multiple variables.
2. Right-click on the selected variable name, choose the “Refactor” option, and then select “Rename” (or simply press “Shift+F6”).
3. In the pop-up dialog box, enter the new variable name you want to change and then click on the “Refactor” button.
4. PyCharm will bulk modify all selected variable names in your code.

Before batch modifying variable names, please make sure you carefully review your code to avoid any unexpected changes.
