What will be the output of the following code?x = [1, 2, 3]x.remove(2)...
Code Explanation
The given code snippet performs a simple operation on a list in Python:
python
x = [1, 2, 3]
x.remove(2)
print(x)
Step-by-step Breakdown
- Initialization: The list `x` is created with the elements `[1, 2, 3]`.
- Remove Operation: The method `remove(2)` is called on the list `x`. This method searches for the first occurrence of the value `2` in the list and removes it. After this operation, the list `x` becomes `[1, 3]`.
- Print Statement: Finally, the updated list `x` is printed, which now contains only the elements `1` and `3`.
Final Output
- The output of the code will be `[1, 3]`.
Correct Answer
- The correct answer is option B: `[1, 3]`.
Why Other Options are Incorrect
- Option A ([1, 2, 3]): This is the original list before the `remove()` method is called, so it's incorrect.
- Option C ([2, 3]): This is not possible as the number `2` is removed from the list.
- Option D (Error: undefined variable): There are no undefined variables in the code; it runs without errors.
Conclusion
- The operation effectively modifies the list by removing the specified element, leading to the final output of `[1, 3]`.
