#41391 — How to add the current dir to sys.path when calling a python file?

Hi,

man python says "If a script  argument  is  given,  the directory
containing the script is inserted in the path in front of $PYTHONPATH.
The search path can be manipulated from  within a Python program as
the variable sys.path." Instead I want to have the current directory
inserted to the front of $PYTHONPATH without changing anything the
script. Is there a way to do so?

No. If you want to manipulate the path, you have to write code to do so, 
and put it in your script. That's very simple:

import os, sys
sys.path.insert(0, os.getcwd())

Actually, it is quite simple. Just use stdin to take the python file.

~/linux/test/python/man/library/sys/path$ cat.sh main.py subdir/main.py
==> main.py <==
#!/usr/bin/env python

import sys

print sys.path

==> subdir/main.py <==
#!/usr/bin/env python

import sys

print sys.path
~/linux/test/python/man/library/sys/path$ diff <(python - < main.py)
<(python - < subdir/main.py)

Have you seen http://docs.python.org/2/library/site.html ?
