Yes: thanks for the correction!
A lesson to me to include parentheses even when redundant...
This reminds me of the following parenthesization gem
(see next to last line):
def isqrt(n):
"""Find the closest integer to sqrt(n), for n a positive
integer."""
a, b = n, 1
while a != b:
a, b = a -- n // a >> 1, a
return a
