Would’ve been easy with fastmod: https://github.com/facebookincubator/fastmod
Or libCST: https://github.com/Instagram/LibCST docs: https://libcst.readthedocs.io/en/latest/ :
> LibCST parses Python 3.0 -> 3.12 source code as a CST tree that keeps all formatting details (comments, whitespaces, parentheses, etc). It’s useful for building automated refactoring (codemod) applications and linters.

> Pymode can rename everything: classes, functions, modules, packages, methods, variables and keyword arguments.

Their README now recommends pylsp-rope:
> If you are using ropevim, consider using pylsp-rope in Vim
python-rope/pylsp-rope: https://github.com/python-rope/pylsp-rope :
> Finding Occurrences: The find occurrences command (C-c f by default) can be used to find the occurrences of a python name. If unsure option is yes, it will also show unsure occurrences; unsure occurrences are indicated with a ? mark in the end. Note that ropevim uses the quickfix feature of vim for marking occurrence locations. [...]
> Rename: When Rename is triggered, rename the symbol under the cursor. If the symbol under the cursor points to a module/package, it will move that module/package files

https://code.visualstudio.com/docs/editor/refactoring#_renam... :
> Rename symbol: Renaming is a common operation related to refactoring source code, and VS Code has a separate Rename Symbol command (F2). Some languages support renaming a symbol across files. Press F2, type the new desired name, and press Enter. All instances of the symbol across all files will be renamed
Because pytest requires a preprocessing step, renaming fixtures is tough, and also for jupyter notebooks %%ipytest is necessary to call functions that start with test_ and upgrade assert keywords to expressions; e.g `assert a == b, error_expr` is preprocessed into `assertEqual(a,b, error_expr)` with an AssertionError message even for comparisons of large lists and strings.
