How to use random to choose colors

Question

I'm trying to make a little program to learn more, but am stuck when it comes to using random.

Here is an example of what I'm going off of https://trinket.io/Python/3338c95430

I've tried using random.randrange, random.choice, random.random with everything for them and it sends an error code saying random doesn't have a function of randrange, choice, or random.

import turtle, math, random, time  wn = turtle.Screen() wn.bgcolor('grey') Rocket = turtle.Turtle() Rocket.speed(0) Rocket.color('red') ## this is what i want to randomize rotate=int(90)  def drawCircles(t,size):     for i in range(15):         t.circle(size)         size=size-10 def drawSpecial(t,size,repeat):     for i in range(repeat):         drawCircles(t,size)         t.right(360/repeat) drawSpecial(Rocket,100,10) 

Eventually I would like to implement more randomized processes like the size and placement but for now I'm just focusing on color.

Answer 1

Without using additional imports it's fairly simple:

turtle.colormode(255) # sets the color mode to RGB  R = random.randrange(0, 256, 100) # last value optional (step)  B = random.randrange(0, 256) G = random.randrange(0, 256)  # using step allows more control if needed # for example the value of `100` would return `0`, `100` or `200` only  Rocket.color(R, G, B) ## randomized from values above 

Using randomized values of (200,255,23):

_{EDIT: Regarding "would i just change the turtle.colormode() to Rocket.colormode() for the next one?"}

The way I would recommend doing it would be to create a function:

def drawColor():      turtle.colormode(255)      R = random.randrange(0, 256)     B = random.randrange(0, 256)     G = random.randrange(0, 256)      return R, G, B  Rocket.color(drawColor()) 

This way you can call drawColor() anytime you want a new color.

Now that you have the basics of randomizing colors for your drawing you can get quite creative with the values for some awesome looking results (adjust integers to your liking):

#!/usr/bin/python  import turtle, math, random, time  def drawColor(a, b, o):     turtle.colormode(255)     R = random.randrange(a, b, o) # last value is step (optional)     B = random.randrange(a, b, o)     G = random.randrange(a, b, o)     # print(R, G, B)     return R, G, B  def drawRocket(offset):     Rocket = turtle.Turtle()     Rocket.speed(0)     Rocket.color(drawColor(20, 100, 1)) # start (0-256), end (0-256), offset      rotate=int(random.randrange(90))     drawSpecial(Rocket,random.randrange(0, 10), offset)  def drawCircles(t,size):     for i in range(30):         t.circle(size)         size = size - 20  def drawSpecial(t,size,repeat):     for i in range(repeat):         drawCircles(t,size)         t.right(360/repeat)  def drawMain(x, y):     wn = turtle.Screen()     wn.bgcolor(drawColor(0, 20, 2))      for i in range(3): # iterations         drawRocket(x)         x+=y         # print(x)  drawMain(2, 10) # offset, step input("Press ENTER to exit")
