Saving changes to path

[Chess Club]

Hello,

I used sys.path.append() to add to the path directory, but the changes
made are not saved when I exit the compiler. Is there a way to save
it?

Thank you.

Since python is running in a child process, it only affects its own
environment variables. I'm not sure that a process can change its
parents' environment variables in a platform independent way.


I also tried:
$ python -c 'import os; os.system("export FOO=1")'
$ echo $FOO

$

but it doesn't seem to work.

Do you mean saved as in your PATH environment variable is now changed?
This would be bad. Not sure about *nix, but on M$ Windows Python's
sys.path has very little in common with PATH.

Or do you mean saved as in the next time you load Python it remembers
what you had in sys.path? Not that I know of. What you can do,
however, is set your PYTHONSTARTUP environment variable to some small
..py script, which Python will run on startup, and put what you want in
there. I.e.:

8<-------------------------------------------------------------------
# Python startup file
import sys
sys.path.append('some_folder')
8<-------------------------------------------------------------------

You can change your prompts, etc.

You might also try IPython (http://ipython.scipy.org/).
