Which Python code snippet correctly removes the first task from a queue list named 'task_queue'?
Atask_queue.pop(0)
Btask_queue.pop()
Ctask_queue.remove(0)
Dtask_queue.delete(0)
Step-by-Step Solution
Solution:
  1. Step 1: Understand list methods for queue

    To remove the first item, pop(0) removes the element at index 0.
  2. Step 2: Check other methods

    pop() removes last item, remove(0) tries to remove value 0, delete() is invalid for lists.
  3. Final Answer:

    task_queue.pop(0) -> Option A
  4. Quick Check:

    Remove first item = pop(0) [OK]
Quick Trick: pop(0) removes first item from list [OK]
Common Mistakes:
  • Using pop() removes last item, not first
  • Using remove(0) tries to remove value zero
  • Using delete() causes syntax error
