Yes, I know it's supported. But I think it'd be better off avoiding it in order to be an elegant path joiner. :) > >> Btw, it seems like python's os.path.join() just use latter if it's an >> absolute path. >> >> $ python >> Python 2.7.3 (default, Jul 24 2012, 10:05:38) >> [GCC 4.7.0 20120507 (Red Hat 4.7.0-5)] on linux2 >> Type "help", "copyright", "credits" or "license" for more information. >> >>> import os.path >> >>> os.path.join('/home/', '/namhyung/') >> '/namhyung/' > > Interesting, wonder what is the rationale for that or if this is a bug. Hmm.. pydoc os.path.join says below: os.path.join = join(a, *p) Join two or more pathname components, inserting '/' as needed. If any component is an absolute path, all previous path components will be discarded. An empty last part will result in a path that ends with a separator.
