Class takes no arguments
#1
Hello guys, I'm learning Python and there is a small problem in writing code for one game. I've created a Ball class with some attributes. And then, when I create a member of this class, I get a TypeError.
from tkinter import *
import random
import time
class Ball:
    def _init_(self, canvas, color):
        self.canvas = canvas
        self.id = canvas.create_oval(10, 10, 25, 25, fill=color)
        self.canvas.move(self.id, 245, 100)
        
    def draw(self):
        pass
    
tk = Tk()
tk.title('Bounce!')
tk.resizable(0, 0)
tk.wm_attributes('-topmost', 1)
canvas = Canvas(tk, width=1800, height=1000, bd=1, highlightthickness=0)
canvas.pack()
tk.update()
ball = Ball(canvas, 'red')
while 1:
    tk.update_idletasks()
    tk.update()
    time.sleep(0.01)

Error:
Traceback (most recent call last): File "D:/Games/скок!.py", line 20, in <module> ball = Ball(canvas, 'red') TypeError: Ball() takes no arguments
Please, help me!

class Ball:
    def _init_(self, canvas, color):
init should have double _
class Ball:
    def __init__(self, canvas, color):
