Using lists (built-in stack methods)

# Initialize an empty list to represent the stack
stack = []

# Push elements onto the stack
stack.append(1)
stack.append(2)
stack.append(3)

# Print the current state of the stack
print("Stack after pushing elements:", stack)

# Pop elements from the stack
popped_element = stack.pop()
print("Popped element:", popped_element)

# Print the current state of the stack after popping
print("Stack after popping:", stack)
