Turtle Problem

[OmarSinno]

I'm drawing a polygon in which every side of that polygon should get a random color, that means that for every side the turtle should get a different color, this is my code:

import turtle
import random
r = 0.0


def cpolygon(n, size, colors):
	angle = 360/n 
	r = random.randint(25, 160)
	for i in range(n):
		turtle.pencolor(str(r))
		turtle.forward(100)
		turtle.left(angle)
	turtle.mainloop()

cpolygon(8, 100, r)

And this is the error:

Error:
turtle.TurtleGraphicsError: bad color string: 98

Help?

if you specify pencolor as string it should be Tk string like 'yellow', 'red' or hexadecimal color like '#33cc8c'
The other option would be to specify RGB tuple

Changed my code to this and it worked like magic:

import turtle
import random
colors=['blue' , 'red', 'orange', 'purple']

def cpolygon(n, size, colors):
	angle = 360/n
	for i in range(n):
		turtle.pencolor(random.choice(colors)) #chooses a random element in the given list 'colors'
		turtle.forward(100)
		turtle.left(angle)
	turtle.mainloop()

cpolygon(8, 100, colors)
