This is not the correct place to report behavioral bugs; this list is
for discussion of the Python documentation (including bug reports
about the docs). Better would be either a post to python-list
(python-list at python.org) or a bug report on bugs.python.org.
However, in this case, there is no bug. You're running into a common
misconception with operator precedence. `-2**4` is evaluated as
`-(2**4)`, that is, "the negation of 2 to the power of 4." To get
"the 4th power of negative 2", you'd need to do `(-2)**4`. See
https://docs.python.org/3/reference/expressions.html#operator-precedence
for more information.
Hope this helps,
