Turtle Race on Python

Still on Day 46

Turtle Race Code:

from turtle import Turtle, Screen
import random

screen = Screen()
screen.setup(width=500, height=400)


start = False
user_bet = screen.textinput(title="Make Your Bet", prompt="Which turtle will win the race? Enter a color: ")
colors = ["red", "orange", "yellow", "green", "blue", "purple"]
all_turtles = []

for color in colors:
    maddy = Turtle(shape="turtle")
    maddy.color(color)
    maddy.penup()
    maddy.goto(-240, -100 + colors.index(color) * 40)
    all_turtles.append(maddy)

if user_bet:
    start = True

while start:

    for turtle in all_turtles:
        if turtle.xcor() > 240:
            start = False
            winning_turtle = turtle.pencolor()
            if winning_turtle == user_bet:
                print(f"You've won! The {winning_turtle} turtle is the winner!")
            else:
                print(f"You've lost! The {winning_turtle} turtle is the winner!")

        random_distance = random.randint(0,10)
        turtle.forward(random_distance)


screen.exitonclick()
