From: Rotwang on 24 Jan 2010 10:08 Hi all, can anybody tell me whether there's a way to change the default location for files to be opened by open()? I'd like to be able to create files somewhere other than my Python folder without having to write the full path in the filename every time. Sorry if this is a stupid question, I don't know much about programming.

So would adding import os os.chdir(<path>) to site.py (or any other module which is automatically imported during initialisation) change the default location to <path> every time I used Python?

First of all you shouldn't alter the site module ever! The optional sitecustomize module exists to make global changes. A library must never change the current working directory. It's up to the application to choose the right working directory. If you mess with the working directory in a library or global module like site you *will* break applications. Python has multiple ways to modify the list of importable locations, either globally, for the current user or the current application. Use them wisely! Christian
