"Start an interactive Python interpreter in another window.
This is like Shell mode, except that Python is running in the window
instead of a shell. See the `Interactive Shell' and `Shell Mode'
sections of the Emacs manual for details, especially for the key
bindings active in the `*Python*' buffer.
With optional \\[universal-argument], the user is prompted for the
flags to pass to the Python interpreter. This has no effect when this
command is used to switch to an existing process, only when a new
process is started. If you use this, you will probably want to ensure
that the current arguments are retained (they will be included in the
prompt). This argument is ignored when this function is called
programmatically, or when running in Emacs 19.34 or older.
Note: You can toggle between using the CPython interpreter and the
JPython interpreter by hitting \\[py-toggle-shells]. This toggles
buffer local variables which control whether all your subshell
