Output Explanation:
The given code creates a list named 'arr' with elements [1, 2, 3, 4, 5]. It then prints a slice of the list using the syntax 'arr[2:4]'.
Understanding Slicing:
When we slice a list, we specify a range of indices to extract a portion of the list. The syntax for slicing is 'start_index:end_index', where the start_index is inclusive and the end_index is exclusive.
In our case, arr[2:4] means that we want to extract a portion of the list starting from index 2 and ending at index 4 (exclusive).
Explanation:
Let's break down the given code step by step:
1. Create a list named 'arr' with elements [1, 2, 3, 4, 5].
2. Print a slice of the list using the syntax 'arr[2:4]'.
The slice 'arr[2:4]' means that we want to extract elements from index 2 to index 4 (exclusive).
- The element at index 2 is 3.
- The element at index 3 is 4.
Therefore, the output of the code will be [3, 4].
Summary:
The given code prints a slice of the list 'arr' starting from index 2 and ending at index 4 (exclusive). This slice includes the elements [3, 4]. Therefore, the correct answer is option C) [3, 4].
