WebPython supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long and is separate from the int type, but the interpreter will automatically use whichever is more appropriate. In Python 3.0+, the int type has been dropped completely.. That's just an implementation detail, though — as long as you have … WebDec 13, 2015 · Any negative number causes a recursion error, for the function being unable to handle them.
