Demonstrate Stack in Python using Class (without Menu Driven)

Program:

class stack:

def __init__(self):

self.items=[]

def push(self,data):

self.items.append(data)

def pop(self):

return self.items.pop()

def peek(self):

l=len(self.items)

return self.items[l-1]

def get_stack(self):

return self.items

#Object of class stack

s=stack()

s.push("A")

s.push("B")

s.push("C")

s.push("D")

s.push("E")

print("Stack=",s.get_stack())

print("Peek value=",s.peek())

print("POP=",s.pop())

print("Current Stack=",s.get_stack())

Expected O/P:

Stack= ['A', 'B', 'C', 'D', 'E']

Peek value= E

POP= E

Current Stack= ['A', 'B', 'C', 'D']
