Can anyone help me modify the code so the ball starts in random directions

[phamtony33 at gmail.com]

Can anyone direct me in the direction where to start the code for the randomized of the  ball  to start.

from Tkinter import *
window = Tk()
canvas = Canvas(window, width=500, height=500, background="green")
canvas.pack()

def mouse_paddle_move(event):
	mouseY = event.y
	current_coords = canvas.coords("paddle")
	x1 = current_coords[0]
	y1 = current_coords[1]
	x2 = current_coords[2]
	y2 = current_coords[3]
	height = (y2 - y1)
	canvas.coords("paddle", x1, mouseY - (height/2), x2, mouseY + (height/2))

def move_ball(speed_x, speed_y, score):
	box = canvas.bbox("ball")
	x1 = box[0]
	y1 = box[1]
	x2 = box[2]
	y2 = box[3]

	
	if x2 >= 500:
		canvas.create_text(250, 250, text="Game Over!")
		return
	
	
	box = canvas.bbox("paddle")
	px1 = box[0]
	py1 = box[1]
	px2 = box[2]
	py2 = box[3]
	if x2 > px1 and y2 > py1 and y1 < py2:
		
		speed_x = -1.2 * (abs(speed_x))
		speed_y = 1.2 * speed_y

		
		score = score + 1
		canvas.itemconfig("score_text", text="Score: " + str(score))
	
	
	if x1 <= 0:
		speed_x = -1 * speed_x
		
	
	if y2 >= 500 or y1 <= 0:
		speed_y = -1 * speed_y
	
	canvas.move("ball", speed_x, speed_y)
	canvas.after(30, move_ball, speed_x, speed_y, score) 


canvas.create_oval(225, 225, 275, 275, fill="blue", tags="ball")
canvas.create_rectangle(450, 200, 455, 300, fill="red", tags="paddle")
canvas.create_text(250, 10, tags = "score_text", text="Score: 0")


move_ball(-10, 7, 0)


canvas.bind('<Motion>', mouse_paddle_move)

mainloop()
