-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.
-
-Note: You can toggle between using the CPython interpreter and the
-JPython interpreter by hitting \\[python-toggle-shells]. This toggles
-buffer local variables which control whether all your subshell
-interactions happen to the `*JPython*' or `*Python*' buffers (the
-latter is the name used for the CPython buffer).
-
-Warning: Don't use an interactive Python if you change sys.ps1 or
-sys.ps2 from their default values, or if you're running code that
-prints `>>> ' or `... ' at the start of a line. `python-mode' can't
-distinguish your output from Python's output, and assumes that `>>> '
-at the start of a line is a prompt from Python. Similarly, the Emacs
-Shell mode code assumes that both `>>> ' and `... ' at the start of a
-line are Python prompts. Bad things can happen if you fool either
-mode.
-
-Warning: If you do any editing *in* the process buffer *while* the
-buffer is accepting output from Python, do NOT attempt to `undo' the
-changes. Some of the output (nowhere near the parts you changed!) may
-be lost if you do. This appears to be an Emacs bug, an unfortunate
-interaction between undo and process filters; the same problem exists in
