...etween the os.path.exists and the os.makedirs calls, so that to protect us from race conditions. In Python 3.2+, there is a more elegant way that avoids the race condition above: import os filename = "/foo/bar/baz.txt" os.makedirs(os.path.dirname(filename), exist_ok=True) with open(filename, "w...
