Summary: PyDoc crashes at os.py line 133
Initial Comment:
Details of the attempted runs are given below:
C:\Python24\Lib>python pydoc.py sys
Help on built-in module sys:
NAME
sys
FILE
(built-in)
MODULE DOCS
http://www.python.org/doc/current/lib/module-sys.html
etc. etc.
------------------------------------------------------------------------------------------------------------
The above works OK but the following - advertised in
the PyDoc.py comment - fails.
-----------------------------------------------------------------------------------------------------------
C:\Python24\Lib>pydoc sys
'import site' failed; use -v for traceback
Traceback (most recent call last):
File "C:\Python24\Lib\pydoc.py", line 54, in ?
import sys, imp, os, re, types, inspect, __builtin__
File "C:\Python24\Lib\os.py", line 133
from os.path import (curdir, pardir, sep, pathsep,
defpath, extsep, altsep,
^
SyntaxError: invalid syntax
------------------------------------------------------------------------------------------------------------
Lines 132 to 134 of os.py:
sys.modules['os.path'] = path
from os.path import (curdir, pardir, sep, pathsep,
defpath, extsep, altsep,
devnull)
------------------------------------------------------------------------------------------------
The above "from X import" usage appears legitimate.

When you write, "pydoc sys", your relying on a file
association for py files to get run by python23. The
association is not controlled by the PYTHON environment
variable.
Anyway, it is evident from the initial report that there is
not a bug. When "python pydoc.py sys" runs fine, it means
that your sys file is okay. When it fails using "pydoc sys"
it means an earlier version of the interpreter is being run
on the Py2.4 sys file. To convince yourself, change to
c:\python23\lib and run "pydoc sys".

I do have Python 2.4 and 2.3 installed but the environment
variable PYTHON is set to C:\Python24.
I have checked to see that no Python process is running
before repeating the test this morning. I get the same results.
Is there any other check I should make?

This is probably invalid. It looks like you may have
multiple python versions running on your system and that the
pydoc batch file is invoking an earlier version of the
interpreter that doesn't understand multiline imports).
