In the virtualenv example bootstrap code, a global join function is used. http://pypi.python.org/pypi/virtualenv
subprocess.call([join(home_dir, 'bin', 'easy_install'), 'BlogApplication']) In interpeter, I tried this: >>> [join([], 'bin', 'easy_install')] Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'join' is not defined I think I've seen this used elsewhere, but googling only seems to show results about the string method join, not whatever this is. To be clear, I understand how to use "".join(list), but have not found any information about this other, seemingly global, join function which takes multiple arguments. It's been bugging me. -- http://mail.python.org/mailman/listinfo/python-list
