![]() Let’s create a simple Stack class that encapsulates the functionality of a stack: class Stack: This approach provides a cleaner, more organized way to handle stacks and can make your code more readable and maintainable. Implementing Python Stack Using a ClassĪs you become more comfortable with Python and stacks, you might find it useful to implement a stack using a class. ![]() Using Python’s list data structure and these two methods, you can easily implement a basic stack and perform the fundamental ‘push’ and ‘pop’ operations. We also print the contents of the stack after the pop operation, showing that the ‘c’ element has been removed. The removed element is stored in the variable ‘last_element’, and we then print this value. In this example, we use the pop() method to remove the last element (‘c’) from the stack. Here’s how you can do it: last_element = stack.pop() This method removes the last element from the list, which corresponds to the top of the stack. To remove an element from the stack (pop operation), you can use the pop() method. The print() function displays the contents of the stack, showing the elements in the order they were added. We then add the elements ‘a’, ‘b’, and ‘c’ to the stack using the append() method. ![]() In this code block, we first create an empty list named ‘stack’. This method adds an element to the end of the list, which corresponds to the top of the stack in our analogy. To add an element to the stack (push operation), you can use the append() method. The key operations in a stack, namely ‘push’ (add an element to the top of the stack) and ‘pop’ (remove an element from the top of the stack), can be easily achieved using the append() and pop() methods of a list. Python’s built-in list data structure is a simple and effective way to implement a stack.
