Today we are going to share a Python code to reverse a string using stack. If you are a python beginner and want to start learning the python programming, then keep your close attention in this tutorial as I am going to share a Python code to reverse a string using the stack.

To increase your Python knowledge, practice all Python programs, here is a collection of 100+ Python problems with solutions.

Python code to reverse a string using stack code

Copy the below python program and execute it with the help of python compiler.

def createStack():

stack=[]

return stack

def size(stack):

return len(stack)

def isEmpty(stack):

if size(stack) == 0:

return true

def push(stack,item):

stack.append(item)

def pop(stack):

if isEmpty(stack): return

return stack.pop()

def reverse(string):

n = len(string)

stack = createStack()

# Push all characters of string to stack

for i in range(0,n,1):

push(stack,string[i])

string=""

for i in range(0,n,1):

string+=pop(stack)

return string

s = "Freewebmentor"

print ("The original string is : ",end="")

print (s)

print ("The reversed string(using stack) is : ",end="")

print (reverse(s))

Output:

The original string is : Freewebmentor
The reversed string(using stack) is : rotnembeweerf
