Question

Is there an equivalent of slime for python?

For example, if I position the cursor on foo() and do M-. (jump to definition) I would like to see the source definition of

Answer 1

M-. normally runs the "find-tag" function. You should create a TAGS file of your python source files. Then you "visit-tags-table" before doing a M-. That way, Emacs will jump to all the definitions of the tag. Type C-u M-. to jump the next definition of your tag. See find-tag documentation for help. Consult Emacs help to know how to create a TAGS file from python source files.

You can for example use Exuberant Ctags for creating the TAGS file.

Go to the root directory of your python files and do this :

ctags -e -R .

A TAGS file is normally created at the root directory of the project.
