Let list1 =[1,2,3,4,5,6]. How to access the last element?list1[-1]list1[5]BothNone

Break Down the Problem

1. We need to understand how to access elements from a list in programming, specifically focusing on the last element of the list.

Relevant Concepts

2. In Python, lists allow indexing from both the front and the back. Negative indexing starts from the end of the list, where -1 refers to the last element. Additionally, direct indexing from the front starts at 0.

Analysis and Detail

3. For the given list list1 = [1, 2, 3, 4, 5, 6]:
   • The last element can be accessed using list1[-1].
   • Alternatively, since the list has 6 elements, the last element can also be accessed using list1[5], as indexing starts at 0.
   • Therefore, both list1[-1] and list1[5] would yield the same result.

Verify and Summarize

4. When checking the two expressions:
   • list1[-1] returns 6
   • list1[5] also returns 6
   • The options "Both" is therefore correct since both methods access the last element.

Final Answer

The correct answer is Both.
