How to make this program in python?

Question

I'm try to make this: your enter a word like this: Happy and than the program returns somethings like : yppaH or appHy.

The problem is that I get just one letter : y or H, etc..

import random
def myfunction():
    """change letter's position"""
    words = input("writte one word of your choice? : ")
    words = random.choice(words)
    print('E-G says : '+ words)

Answer 1

You have to use sample, not choice.

import random
# it is better to have imports at the beginning of your file
def myfunction():
    """change letter's position"""
    word = input("writte one word of your choice? : ")
    new_letters = random.sample(word, len(word))
    # random.sample make a random sample (without returns)
    # we use len(word) as length of the sample
    # so effectively obtain shuffled letters
    # new_letters is a list, so we have to use "".join
    print('E-G says : '+ "".join(new_letters))

Answer 2

If you want to print reversed word this would be fastest approach:

print(input("writte one word of your choice? : ")[::-1])

Answer 3

Use random.shuffle on a conversion of the string in a list (works in-place)

Then convert back to string using str.join

import random

s =  "Happy"

sl = list(s)
random.shuffle(sl)

print("".join(sl))

outputs:

pyapH
Hpayp
