Learn how to implement stack data structure in Python with examples and code snippets. Understand push, pop, and peek operations.

Here is an implementation of the Stack ADT that uses a Python list: class Stack : def __init__ ( self ): self . items = [] def push ( self , item ): self . items . append ( item ) def pop ( self ): return self . items . pop () def is_empty ( self ): return ( self . items == [])

Aug 28, 2023 · Using a Python List. The Python list-based implementation of the Stack ADT is the easiest to implement. The first decision we have to make when using the list for the Stack ADT is which end of the list to use as the top and which as the base.

STEP 1: Create a Stack [], Queue[],List[] with MAX size as your wish. STEP 2 : Write function for all the basic operations of stack, Queue, List - PUSH(), POP() and DISPLAY(),append(),Extend().

Implementation of a stack ADT using Array Stack and Array Deque to allow amortized constant time regular push, regular pop and pushing in the middle of the stack.
