I can not understand why writes an error?

Question

Python

I am writing a program, but I ran into an error, I want that when I click on the button with the name "btn2" the Words1 and Words2 variables change their value. And at the same time, when you press the "btn" button, the Words1 variable randomly shuffles. Here is the whole code:

from tkinter import *
import time
import random

tk = Tk()
canvas = Canvas(tk, width=1000, height=800)
tk.resizable(0, 0)
my_background = PhotoImage(file=r'D:\\prog\\Darkand\\background.gif')
w = my_background.width()
h = my_background.height()
errors = 0
for x in range(0, 5):
    for y in range(0, 5):
        canvas.create_image(x * w, y * h, image=my_background, anchor='nw')
Words2 = ('Press a difficulty button')
Words1 = ('Press a difficulty button')


def Easy():
    Words2 = ('Огонь', 'Слово', 'Три', 'Молоко', 'Пять', 'Кошка')
    Words1 = ('огонь', 'слово', 'три', 'молоко', 'пять', 'кошка')
    pass

btn2 = Button(tk, text='Easy', command=Easy())
btn2.pack()
tk.update()


def words():
    random.shuffle(Words1)
    time.sleep(0.02)
    canvas.create_text(230, 600, text=Words1, font=('Helvetica', 20))
    Guess = str(input('Введи Слово 1:')).strip()
    if Guess == Words2[0] or Words1[0]:
        canvas.create_arc(700, 700, 50, 50)
        canvas.create_text(100, 300, text="Правильно!", font=('Helvetica', 20))
    else:
        canvas.create_text(100, 300, text="Неправильно!", font=('Helvetica', 20))
    Guess = str(input('Введи Слово 2:')).strip()
    if Guess == Words2[1] or Words1[1]:
        print('123')
        canvas.create_text(100, 300, text="Правильно!", font=('Helvetica', 20))
    else:
        canvas.create_text(100, 300, text="Неправильно!", font=('Helvetica', 20))
    Guess = str(input('Введи Слово 3:')).strip()
    if Guess == Words2[2] or Words1[2]:
        canvas.create_text(500, 300, text="Правильно!", font=('Helvetica', 20))
    else:
        canvas.create_text(100, 300, text="Неправильно!", font=('Helvetica', 20))
    Guess = str(input('Введи Слово 4:')).strip()
    if Guess == Words2[3] or Words1[3]:
        canvas.create_text(500, 540, text="Правильно!", font=('Helvetica', 20))
    else:
        canvas.create_text(100, 320, text="Неправильно!", font=('Helvetica', 20))
    Guess = str(input('Введи Слово 5:')).strip()
    imagethree = PhotoImage(file=r'D:\\prog\\Darkand\\three.gif')
    canvas.create_image(30, 500, image=imagethree, anchor='nw')
    if Guess == Words2[4] or Words1[4]:
        canvas.create_text(500, 540, text="Правильно!", font=('Helvetica', 20))
    else:
        canvas.create_text(100, 320, text="Неправильно!", font=('Helvetica', 20))
    Guess = str(input('Введи Слово 6:')).strip()
    if Guess == Words2[5] or Words1[5]:
        canvas.create_text(500, 540, text="Правильно!", font=('Helvetica', 20))
    else:
        canvas.create_text(100, 320, text="Неправильно!", font=('Helvetica', 20))


def clear():
    errors = 0
    canvas.delete("all")
    for x in range(0, 5):
        for y in range(0, 5):
            canvas.create_image(x * w, y * h, image=my_background, anchor='nw')
    canvas.pack()
    tk.update()


b = Button(tk, text="Clear", command=clear)
btn = Button(tk, text="Words", command=words)
canvas.pack()
btn.pack()
b.pack()
tk.update()
tk.mainloop()


def __init__():
    pass

It writes the following error:
Exception in Tkinter callback
Traceback (most recent call last):
File "D:\prog\lib\tkinter\__init__.py", line 1705, in __call__
return self.func(*args)
File "D:/ prog/Darkand/Darkandv2test.py", line 30, in words
random.shuffle(Words1)

TypeError: 'str' object does not support item assignment

Answer 1

Words1 =['Огонь', 'Слово', 'Три', 'Молоко', 'Пять', 'Кошка']
