Python 25 Line Challenge

[Gribouillis]

I humanized the bouncing balls and made it 25 lines long.

import tkinter, time, math, random, dataclasses
Ball = dataclasses.make_dataclass('Ball', ('shape', 'x', 'y', 'spdx', 'spdy', 'color'))
def onTimer():
    for i, ball in enumerate(ballstats):
        ball.x += ball.spdx
        ball.y += ball.spdy
        for other in ballstats[i+1:]:
            dist = math.sqrt((ball.x - other.x)**2 + (ball.y - other.y)**2) 
            if dist < balldiameter:
                ball.spdx, other.spdx = other.spdx, ball.spdx
                ball.spdy, other.spdy = other.spdy, ball.spdy
        if ball.x < 0 or ball.x > winWid - balldiameter: ball.spdx = - ball.spdx
        if ball.y < 0 or ball.y > winHei - balldiameter: ball.spdy = - ball.spdy
        canvas.coords(ball.shape, (ball.x, ball.y, ball.x + balldiameter, ball.y + balldiameter))
    timerhandle = window.after(2,onTimer)
winWid, winHei = 640, 480
balldiameter = 7
window = tkinter.Tk()
canvas = tkinter.Canvas(window, width=winWid, height=winHei, bg="white")
canvas.pack()
ballstats = [Ball(None, random.randrange(0, winWid), random.randrange(0, winHei), random.random() * 2 - 1, random.random() * 2 - 1, "#" + ''.join(random.choices("0123456789ABCDEF", k=6))) for i in range(100)]
for ball in ballstats:
    ball.shape = canvas.create_oval(ball.x, ball.y, ball.x + balldiameter, ball.y + balldiameter, outline=ball.color, fill=ball.color)
timerhandle = window.after(2,onTimer)
window.mainloop()

Some lines are too long. Normally I don't write lines larger than 80 characters.
