Do you understand what lambda does in general?

Does it help if I rewrite the code like this:

def onQuit(w):
   gtk.main_quit()
button.connect("clicked", onQuit)

?

Provided you get your indentation correct ("def onQuit" and
"button.connect" should be at the same level), and provided you aren't
using the name "onQuit" somewhere else in that method, this code
should be a dropin replacement for the line you quote.
