Why does 0 ** 0 equal 1 in Python? Shouldn’t it throw an exception, like 0 / 0 does?
Wikipedia has interesting coverage of the history and the differing points of view on the value of
0 ** 0:As applied to computers, IEEE 754 recommends several functions for computing a power. It defines
pow(0, 0)andpown(0, 0)as returning1, andpowr(0, 0)as returningNaN.Most programming languages follow the convention that
0 ** 0 == 1. Python is no exception, both for integer and floating-point arguments.
