Error in a minimal tkSimpleDialog example

Question

I was trying out a python code example at Rosetta Code - a programming chrestomathy site, where solutions to the same task are presented in as many different programming languag

Answer 1

I've never used askinteger, but judging from the error message it looks like the dialog needs to know its parent but you're not telling it what its parent should be. Try adding parent=widget (where "widget" is a reference to some other widget -- typically the root widget). I can't find any documentation that says this is required, but I'm guessing it is since all Tkinter widgets except the root window need to have a parent.

If the code you show in your question is the complete code, you're missing some other things. You need to create an instance of the Tk class (called the "root" window), and you need to start the event loop (though, it's possible that the dialog runs it's own event loop, so you might be OK if all you need is the single dialog).
