Re: How to test if a key in a dictionary exists?

Sure, you can use "if key in dict" to test for membership: Python 2.3.5 (#1, Jan 13 2006, 20:13:11) [GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> exampledict = {"a" : 1, "b" : 2} >>> "a" in exampledict True >>> "

Curious behaviour of Tkinter object
