Import to Python

Question

Can I import modules based on location?

(for example, all the modules I import should be in / usr / lib64 / python2.5 / or a similar directory?)

I would like to import a module, local, into the current script.

Answer 1

You can extend the runtime path as follows:

sys.path.extend(map(os.path.abspath, ['other1/', 'other2/', 'yourlib/']))

Answer 2

You can edit PYTHONPATH to add or remove locations that python will look for when you try to import.
