How to - import code not in current directory

[py]

I have a python script that I want to test/debug. It contains a class
which extends from some other class which is located in some other
python file in a different directory.

For example:

[script to test]
c:\python_code\ foo.py

[needed python files]
c:\some\other\d irectory\bar.py

....so I want to test/debug foo.py, which needs bar.py. foo.py imports
bar.py ...but in order to test out foo (in the python shell) I normally
copy bar.py into the same directory as foo.py...but this is painful.
Is there some way that I can have python know about the directory where
bar.py is located, like a system variable, etc? If so, how do I set
that up?

Thanks.

You can locate them with os.walk and fnmatch. Then you can temporarily
add the directory to sys.path, and import using __import__().
"

so this should work in your case:

import sys
sys.path.append ("C:\some\other \directory")
import bar

so this should work in your case:

import sys
sys.path.append ("C:\some\other \directory")

....that will certainly work. Only issue is that each time I start up
foo.py in the python shell I have to retype those three lines....kind
of why I was hoping for a environment variable or path setting that i
could stick in.

This will do for now...

That would be PYTHONPATH.

Re: How to - import code not in current directory

PYTHONPATH is perfect....chec k out this link for more info..

http://docs.python.org/tut/node8.html#searchPath

I just added the environment variable (on windows) named "PYTHONPATH "
and set it to "C:\some\other\ directory"
