Function: run-python

run-python is an autoloaded, interactive and byte-compiled function defined in python.el.gz.

Signature

(run-python &optional CMD DEDICATED SHOW)

Documentation

Run an inferior Python process.

Argument CMD defaults to python-shell-calculate-command return value. When called interactively with prefix-arg, it allows the user to edit such value and choose whether the interpreter should be DEDICATED for the current buffer. When numeric prefix arg is other than 0 or 4 do not SHOW.

For a given buffer and same values of DEDICATED, if a process is already running for it, it will do nothing. This means that if the current buffer is using a global process, the user is still able to switch it to use a dedicated one.

Runs the hook inferior-python-mode-hook after comint-mode-hook is run. (Type C-h m (describe-mode) in the process buffer for a list of commands.)
