[Python] How to make this wheel spin?

I have created the wheel, but when I try to make code to spin it will not work.

I have already tried to make it using a loop but that was near impossible for me. I am basically drawing the wheel over. Here is some code from the spinning wheel part:

turtle.listen()
if turtle.onkeypress("space"):
colors = ['#880000','#884400','#884400','#888800',
'#888800','#008800','#008800','#008800',
'#008800','#008800','#008888','#008888',
'#008888','#008888','#008888','#000088',
'#000088','#000088','#000088','#000088']

for color in colors:
slice_angle = 360 / len(colors)
heading, position = 90, (center[0] + radius, center[1])
turtle.color(color, color)
turtle.speed(0)
turtle.penup()
turtle.goto(position)
turtle.setheading(heading)
turtle.pendown()
turtle.begin_fill()
turtle.circle(radius, extent=slice_angle)
heading, position = turtle.heading(), turtle.position()
turtle.penup()
turtle.goto(center)
turtle.end_fill()
turtle.penup()

time.sleep(0.2)
colors = ['#884400','#884400','#888800',
'#888800','#008800','#008800','#008800',
'#008800','#008800','#008888','#008888',
'#008888','#008888','#008888','#000088',
'#000088','#000088','#000088','#000088','#880000']
for color in colors:
slice_angle = 360 / len(colors)
heading, position = 90, (center[0] + radius, center[1])
turtle.color(color, color)
turtle.speed(0)
turtle.penup()
turtle.goto(position)
turtle.setheading(heading)
turtle.pendown()
turtle.begin_fill()
turtle.circle(radius, extent=slice_angle)
heading, position = turtle.heading(), turtle.position()
turtle.penup()
turtle.goto(center)
turtle.end_fill()
turtle.penup()

time.sleep(0.2)


The code keeps on going to make the wheel 'spin'.

This is what I get:

Exception in Tkinter callback
