Bases: Function

Implementation of logical AND (&).

This class represents a logical AND operation that can be performed on two or more arguments. It supports chaining of multiple AND operations using the & operator.

Parameters:

Name Type Description Default
*args Any

The arguments to be logically ANDed together. At least two arguments are required.

 ()

Raises:

Type Description
ValueError

If fewer than two arguments are provided.

Examples:

>>> a = And(Label.key == "k1", Label.value == "v1")
>>> b = And(Label.key == "k1", Label.value == "v2")
>>> c = a & b

Methods:

Name Description
__and__

Supports chaining of multiple And operations using the & operator.
