[Solved] variable positional and printing the values

Question

The first output shows a comma because without it, 1 being the only element, (1) would be just a integer (parentheses are wrapping the expression 1), (1,) is shown to differentiate tuples and simple parentheses.

in the second one, no trailing comma is needed to differentiate tuples, since there are more than one element.

In the third O/p, you are not passing 1 and 2, but instead you’re passing the whole (1,2), so it shows only one item (which is (1,2)) in a tuple, and adds an extra comma. Same for the fourth: your passing the entire ((1,2), (3,4)).
