What is the output of the following code?my_list = [1, 2, 3]my_list.ap...
Understanding the Code
The provided code snippet performs a simple operation on a list in Python. Let's break it down step by step.
Code Analysis
python
my_list = [1, 2, 3]
my_list.append(4)
print(my_list)
- Initialization: The list `my_list` is created with three elements: `1`, `2`, and `3`.
- Appending an Element: The `append` method is called on `my_list` with the argument `4`. This method adds `4` as the last element of the list.
- Printing the List: Finally, the modified list is printed using `print(my_list)`.
Expected Output
- After appending `4`, the list now contains four elements: `[1, 2, 3, 4]`.
Conclusion
The output of the code will be:
- Option B: `[1, 2, 3, 4]`
This is because the `append` method directly modifies the original list by adding the new element at the end, resulting in the final list being `[1, 2, 3, 4]`.
Understanding this process clarifies how list operations work in Python, particularly the use of the `append` method to extend a list's contents.
