Description:

def take_while(self, predicate):
        '''Returns elements from the start while the predicate is True.

        Note: This method uses deferred execution.

        Args:
            predicate: A function returning True or False with which elements
                will be tested.

        Returns:
            A Queryable over the elements from the beginning of the source
            sequence for which predicate is True.

        Raises:
            ValueError: If the Queryable is closed()
            TypeError: If the predicate is not callable.
