Consider the tuple A=((1),[2,3],[4]), that contains a tuple and list. What is the result of the following operation A[2][0]?

To analyze the operation A[2][0] with the given tuple A = ((1), [2, 3], [4]), let's break it down step by step.

1. Identify the Structure of the Tuple

The tuple A consists of three elements:

1. A[0] = (1) - This is a tuple containing the integer 1.
2. A[1] = [2, 3] - This is a list containing the integers 2 and 3.
3. A[2] = [4] - This is another list containing the integer 4.

2. Accessing the Element

We need to evaluate the expression A[2][0]:

• First, A[2] accesses the third element of the tuple A, which is [4].
• Next, [0] accesses the first element of the list [4].

3. Result

The first element of the list [4] is 4.

Final Answer

The result of the operation A[2][0] is 4.
