Stacks python3 abstract data types

Ok so I am trying to input "Hello World!" and I want the output to be "dlroW olleH" My code prints the opposite one by one. How do I fix this?

class Stack:

    def __init__(self):
        self.__items = []

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

    def pop(self):
        return self.__items.pop()

    def peek(self):
        return self.__items[len(self.__items)-1]

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

    def size(self):
        return len(self.__items)
    def __len__(self):
        return len(self.__items)


x = Stack()

userinput = input("enter ")
for letter in userinput:
    x.push(letter)


while x:
    print(x.pop())

By default, every call to print() writes to a new line on the screen.

You can change this with the end argument to print(), like so:

print(x.pop(), end='')

Then, all of the characters in the string will be printed all on the same line.

You can also add a plain call to print() at the end to add a final end-of-line.
