Add your funny or surprising Python error messages to this thread. A requirement is that you should also show (minimal) code that produces the message. Put the code below, so people can think about how to generate the message first, a little puzzle if you like.
Perhaps this will even be a useful thread, to brighten the life of the brave people doing the hard work of providing us with error messages. My first one (i'm learning, i'm learning) is TypeError: 'callable-iterator' object is not callable # # # # # >>> it = iter(lambda:0, 0) # >>> it() # TypeError: 'callable-iterator' object is not callable -- http://mail.python.org/mailman/listinfo/python-list
