Well, it really should have behaved like mkdir -p in the first place. Eric Raymond submitted the code ages ago, and at the time I wasn't familiar with mkdir -p, otherwise, I would have made him change it. I believe every single use of os.mkdirs() I've made goes something like this: if not os.path.exists(x): os.mkdirs(x) or perhaps like this: try: os.mkdirs(x) except os.error: pass (Though the latter masks a bunch of other rare but possible failure modes -- often this is in throw-away code though where it doesn't matter or the next line will raise an exception that's good enough to diagnose the situation anyway.) -- --Guido van Rossum (python.org/~guido) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
