How can I replace multiple strings in PyCharm?

In PyCharm, you can replace strings in bulk using the following steps:

1. Open PyCharm and navigate to the file or project where you want to replace the string.
2. Press the keys Ctrl, Shift, and R at the same time.
3. Pressing Command + Shift + R
4. In the dialog box, you can enter the string you want to search for and the string you want to replace it with. Choose the scope of the search, which can be the current file, the entire project, or a custom range.
5. Choose alternative options, such as distinguishing between upper and lower case, regular expressions, etc.
6. Click on the “Replace” button to start batch replacement.

Please make sure to back up your files before performing a bulk replacement to prevent accidental modifications. Additionally, PyCharm offers other features such as finding and replacing the history records to view previous replacement operations.
