Steven D'Aprano <steve+pyt...@pearwood.info> added the comment:
This is not a bug, it is normal handling of `and` and `or` operators since
Python 1.5 and possibly older.
The `and` and `or` operators are *short-cut* operators. This is intentional
design, so we can write things like:
if mylist and mylist[0] == value:
the `mylist[0] == value` expression is only evaluated if `mylist` is a truthy
value.
This is all documented here:
https://docs.python.org/3/reference/expressions.html#boolean-operations
