	`161`	+The `zip()` function returns a `zip` object, which is an iterator of tuples where the first item in each passed iterator is paired together, and then the second item in each passed iterator are paired together etc.
	`162`	`+`
	`163`	`+If the passed iterators have different lengths, the iterator with the least items decides the length of the new iterator.`
