New submission from Andre Roberge: According to the docs, and consistent with the Python 2.x behavior, filehandle.write() should return None. However, under 3.0a2 (and 3.0a1), it returns the number of characters written.
Either the documentation http://docs.python.org/dev/3.0/tutorial/inputoutput.html#reading-and-writing-files is wrong, or it is a bug. I would *much* prefer if the behavior would stay the same as before. Below is a sample session illustrating the behavior. Note that I also get an error message when exiting the session using exit() - this is an unrelated problem.
