This may be subtle if there are two different -extensions of the real numbers. For example, :class:`fractions.Fraction` -implements :func:`hash` as follows:: - - def __hash__(self): - if self.denominator == 1: - # Get integers right. - return hash(self.numerator) - # Expensive check, but definitely correct. - if self == float(self): - return hash(float(self)) - else: - # Use tuple's hash to avoid a high collision rate on - # simple fractions. - return hash((self.numerator, self.denominator)) +extensions of the real numbers.
