pyarrow.compute.and_not_kleene¶

pyarrow.compute.and_not_kleene(x, y, *, memory_pool=None)¶ Logical ‘and not’ boolean values (Kleene logic).
This function behaves as follows with nulls:
true and null = null
null and false = null
false and null = false
null and true = false
null and null = null
In other words, in this context a null value really means “unknown”, and an unknown value ‘and not’ true is always false, as is false ‘and not’ an unknown value. For a different null behavior, see function “and_not”.
- Parameters
x (Array-like or scalar-like) – Argument to compute function
y (Array-like or scalar-like) – Argument to compute function
memory_pool (pyarrow.MemoryPool, optional) – If not passed, will allocate memory from the default memory pool.
