Where is the document of python-mode.el

I searched in the python-mode.el, sf.net, python.org, and found nothing

I searched in the python-mode.el, sf.net, python.org, and found nothing

what document?

if you want documentation, switching to a python buffer and typing
alt-X followed by "describe-mode" works for me (alternatively, press
control-H followed by M):

...

Python mode:
Major mode for editing Python files.

...

This mode knows about Python indentation, tokens, comments and
continuation lines. Paragraphs are separated by blank lines only.

COMMANDS
key binding
--- -------
ESC Prefix Command
LFD py-newline-and-indent
DEL py-delete-char
...

to get detailed information about a given command, use describe-key
or describe-function. e.g. "describe-key backspace" (=DEL on my key-
board) gives me:

DEL runs the command py-delete-char:

Reduce indentation or delete character.
If point is at the leftmost column, deletes the preceding newline.

Else if point is at the leftmost non-blank character of a line that is
neither a continuation line nor a non-indenting comment line, or if
point is at the end of a blank line, reduces the indentation to match
that of the line that opened the current block of code. The line that
opened the block is displayed in the echo area to help you keep track
of where you are. With numeric count, outdents that many blocks (but
not past column zero).

Else the preceding character is deleted, converting a tab to spaces if
needed so that only a single column position is deleted. Numeric
argument delets that many characters.

for variables, use describe-variable. e.g. "describe-variable py-indent-
offset" displays:

py-indent-offset's value is 4

Documentation:
*Indentation increment.
Note that `C-c :' can usually guess a good value
when you're editing someone else's Python code.

(all this text comes from the python-mode.el file, so I'm a bit surprised
that you didn't find anything by looking inside it).

(if you need installation help, see the comments at the top of the python-
mode.el file. look for the "INSTALLATION" heading)
