No. That's just not how Python works. [*] However, you can simply import foo from a explicitly within b. Though you might want to rethink what you're doing. Maybe. % cat a.py foo = 'Meh.' import b % cat b.py from a import foo print(foo) % python a.py Meh. % - Thomas [*] Actually, it is possible with runpy. But don't. Really, don't, unless you have a very good reason to do so, and judging by the way the question was asked, I don't think you do. -- http://mail.python.org/mailman/listinfo/python-list
