No syntax highlighting in python mode

No syntax highlighting in python mode

[Tim Johnson]

I'm using GNU Emacs 23.1.1 on Slackware linux 13.0 32-bit.
Syntax highlighting does not work. The only thing highlighted are
strings. Not even function definitions.

I've tried add-hook with 
(setq font-lock-maximum-decoration 
  '((python-mode . 3)))

I've started emacs with a python file and --debug-init
with no messages that suggest any type of error.

c-h, v font-lock-maximum-decoration gives me 
[no match]

Any suggestions would be appreciated. Other programming 
modes work fine. Other python mode functions appear to
work as expected.

thanks

  Hmm! See
	http://www.emacswiki.org/emacs/PythonMode
	where is says: 
	"""
	Emacs post version 21 has its own python mode (python.el). This is
	enabled by default for .py files so you don?t have to add anything to
	your InitFile to use it. 
	"""
  I believe the statement above is incorrect. I had to use the
	require form - I.E. (require 'python) to activate the syntax
	highlighting.
	cheers

I can't reproduce that.  In fact:

emacs -q /usr/share/yum-cli/yumcommands.py

gives me python-mode *with* syntax color.  
[Also on 23.1.1]

  Then I withdraw this statement:

  My problem may be from a side effect of something else in my .emacs
	or other configuration.

It may be something not under your own control, however.
In particular, some OS distributions add their own local 
configurations to their emacs installations.

I recommend doing the same test I did.  If it has the same
problem you saw with your configuration, try the option
"--no-site-file" as well.

  Done. And with the --no-site-file option syntax highlighting
	is the same. However, using -q
	(--no-init-file, -q          load neither ~/.emacs nor default.el)
	I have highlighting.
	I could probably find the problem by going thru my .emacs line by
	line, but I'm happy just to use 'require.
	thanks again
