Then how do I get the old behavior?
Just pass 0 or 1 argument.
(I've been known to do odd things - like change behavior based on the number of args - in extension modules, but this ain't an extension).
It *is* a built-in method. It will be handled just like dictionaries handle the second argument to get.
d.get(nonexistantkey) does not throw an exception, it returns None.
Oops, I'd forgotten that.
If list.pop() does not throw an exception when list is empty, it's new behavior.
Which are you asking for: breaking code that expects IndexError
No.
Violating Pythonic expectations by, in effect, creating 2 methods list.pop(void) list.pop(default_return)
Yes, except that I disagree that this is non-pythonic. Jim -- Jim Fulton mailto:jim@digicool.com Python Powered!
