I think that would be a difficult thing to do in a generic way. The potential for inadvertant data loss is very high. > I've ended up writing my own function to do it, I assume you mean something like: def forceInt(v, default=42): try: result = int(v) except: result = default return result but if you do class C: # lots of stuff in here pass c = C() v=forceInt(c) You could lose all the data in C. I suppose that if you make the default non defaulted - so you have to provide a default - that would be better, the default could then be the object itself v = forceInt(c,c) Is that what you mean?

No, there is no built-in for this but it's easy to write your own: def my_int(value, default): try: return int(value) except ValueError: return default Kent ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] Force a value to int
Is there a particular way to force a value to be an int by either converting it with int() or returning a default value. I've ended up writing my own function to do it, but it seems like the kind of thing that would be built-in somewhere.
