5.9. Logical operators

We already learned Python’s logical operators not, or, and and. Unfortunately, these operators work only on booleans, not on arrays of booleans. However, NumPy provides equivalent operators:

Python’s operator on bool	NumPy’s equivalent operator for arrays of bool
not	~
or	|
and	&

Fig. 5.8 illustrates the behaviour of each operator.
