Emacs

Emacs is a free, open-source, highly extensible text editor and computing environment. Its core is an Emacs Lisp interpreter, which is why Emacs can be customized and extended so deeply.

It supports buffers and windows (splits), programming-language modes with indentation and syntax highlighting, shells, and interacting with tools like debuggers.

For Python, Emacs provides editing support and can run Python’s debugger, pdb. For IDE-like features, such as completion, diagnostics, and go-to-definition, you can use an LSP client like Eglot together with a Python language server.
