What will be the output?>>>t=(1,2,4,3)>>>t[1:3]  (1, 2)(1, 2, 4)(2, 4) (2, 4, 3)

The output will be (2, 4).

Here's the step by step explanation:

1. You have a tuple t which is (1,2,4,3).
2. You are trying to access elements from index 1 to index 3 (excluding 3) of the tuple.
3. In Python, indexing starts from 0. So, index 1 is the second element which is 2 and index 3 is the fourth element which is 3. But since the end index is exclusive in Python, it will not include the element at index 3.
4. Therefore, it will return the elements at index 1 and 2, which are 2 and 4 respectively. Hence, the output will be (2, 4).
