An OverflowError is emitted in case the return value of __len__ exceeds 231-1. The following code: class C (object): def __len__ (self): return self.l c = C() c.l = 231 len (c) # leads to an OverflowError in the last line. It works flawless for c.__len__ ()

An OverflowError is emitted in case the return value of __len__
