Yes. The whole point of being able to use a file as a context manager is so that the file will be closed immediately upon leaving the with statement, whether by falling off the end, "return", an exception, or whatever. IOW, it's like calling .close() immediately after the "with" block, only more so, i.e. it will also handle cases that an explicit .close() misses. -- http://mail.python.org/mailman/listinfo/python-list
