python stack

Comment

from collections import deque

the_stack = deque()

# this function can serve as push
the_stack.append("data")
print(the_stack.pop()) # -> data

# Check out the documents for more features coming when using that dedicated
# builtin.

# About deque: Deques are a generalization of stacks and queues
# (the name is pronounced “deck” and is short for “double-ended queue”).
# Deques support thread-safe, memory efficient appends and pops from either
# side of the deque with approximately the same O(1) performance in either
# direction.

implement stack in python

Comment

class Stack:
    def __init__(self):
        self.stack = []

    def push(self, item):
        self.stack.append(item)

    def pop(self):
        if not self.is_empty():
            return self.stack.pop()

    def peek(self):
        if not self.is_empty():
            return self.stack[-1]

    def is_empty(self):
        return len(self.stack) == 0

    def size(self):
        return len(self.stack)

# Example usage:
stack = Stack()
stack.push(1)
stack.push(2)
stack.push(3)
print(stack.pop())  # Output: 3
print(stack.peek())  # Output: 2
print(stack.size())  # Output: 2
