How to change the variable name all at once?

JupyterLab
1

I know that ctrl + F will find the texts that I want, and I can change variable names accordingly.

However, is there any function or buttons that supports changing all the variable name all at once, as we do in other non-browser based IDEs?

Yes, both the text editor and the notebook viewer in JupyterLab have Find-and-Replace all as an option.
You need to toggle the little drop-down indicator that is to the left of where you enter the search text in order to bring up the ‘Replace’ options.

Here is the text editor in action:

Here is the notebook viewer as you edit cells in action:

find_replace_notebook_example

If you’d to see what you should be seeing, go here and select ‘Try JupyterLab’.
These examples came from there just now. It is running JupyterLab 3.2.0. If you have a JupyterLab version that is 3 or above, then it is really worth updating.

jupyterlab-lsp has the rename feature too, which will only replace code occurrences*:

*the behaviour will vary depending on the language server you choose.

Thank you for your suggestion. “jupyterlab-lsp”, is it a jupyterlab extension? I have visited the github repo page of it, but cannot really figure it out.
