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.
Stack Data Structure – A stack is a collection of elements that follows the Last In First Out (LIFO) principle, where the last element added is the first one to be removed.
Python Lists – In Python, lists are versatile data structures that can be used to implement stacks using methods like append() and pop().
