Questions & Step-by-Step Solutions

In Python, which built-in data structure can be used as a stack?
  • Step 1: Understand what a stack is. A stack is a data structure that follows the Last In, First Out (LIFO) principle.
  • Step 2: In Python, you can use a list to create a stack.
  • Step 3: To add an item to the top of the stack, use the append() method. For example, my_stack.append(item).
  • Step 4: To remove the top item from the stack, use the pop() method. For example, my_stack.pop() will remove and return the last item added.
  • Step 5: Remember that the last item you add to the stack is the first one to be removed.
