It's only an error if it's documented that way and, more importantly, thought of that way. The re module is a good example: if it can't find what you're looking for it returns None -- it does *not* raise a NotFound exception.

But open() raises IOError. ''.find('a') returns -1 but ''.index('a') raises ValueError. So we can argue in circles both ways, there are too many arguments pro and contra. Python is just too inconsistent to be consistently argued over. ;-) Oleg. -- Oleg Broytman http://phdru.name/ phd@phdru.name Programmers don't die, they just GOSUB without RETURN.
