yield tuple

A yield tuple is a sequence of values that are returned by a generator function using the yield keyword. The values in the tuple can be of any data type and can be returned one at a time, or all at once as a single tuple. Here is an example of a generator function that yields a tuple:

def generate_tuples():
    for i in range(5):
        yield (i, i * 2)

for tup in generate_tuples():
    print(tup)

Output:

(0, 0)
(1, 2)
(2, 4)
(3, 6)
(4, 8)

In this example, the generator function generates tuples containing two values - the first value is the loop variable `i`, and the second value is `i` multiplied by 2. The tuples are returned one at a time using the `yield` keyword, and are printed in a loop.
