[issue28529] 0 ** 0 should raise ArithmeticError

[Tim Peters]

Tim Peters added the comment:

This won't be changed - it's a near-universally mandated behavior across relevant standards.  Many years ago it wasn't, but Knuth changed minds when he wrote:

"""
We must define x^0=1 for all x, if the binomial theorem is to be valid when x=0 , y=0 , and/or x=-y . The theorem is too important to be arbitrarily restricted!
"""
