I need a new random color for every new smaller square. Now it changes color only after while loop. Could you help me fix it?

def random_color():
    colvar=random.randint(0,10)
    L=['red','blue','green','yellow','black','pink','gold','violet','coral','lemon chiffon','sea green'] #wiki.tcl.tk/16166  website which I used to find names for colors
    result=L[colvar]
    return result

def square(color,x,y):     
     turtle.color(color)
     turtle.begin_fill()
     turtle.penup()
     turtle.goto(x,y)
     turtle.pendown()
     line1=200           #creates a new smaller square
     while line1>=10:   
      line1=line1-10
      for i in range(2):
          turtle.forward(line1)
          turtle.right(90)
          turtle.forward(line1)
          turtle.right(90)

def drawsqr():
    num=5               
    for i in range(num):  
              color=random_color()  #change color after each complete cycle
              x=250
              y=250
              square(color,x,y)

I understand you solved your issue, but random.choice() is better suited in your function:

def random_color():
    L=['red','blue','green','yellow','black','pink','gold','violet','coral','lemon', 'chiffon','seagreen'] 
    return random.choice(L)

turtle graphics - Draw squares in random colors using Python, I need a new random color for every new smaller square. Now it changes color only after while loop. Could you help me fix it? def random_color():  This problem can be approached several different ways using turtle. Although the obvious answer seems to be nested loops to draw the squares, below are some other ways to think about it. First, using turtle.circle(steps=4). The circle routine can draw arbitrary regular polygons including squares though you have to make adjustments with respect

I understand you solved your issue, but random.choice() is better suited in your function:

I disagree. The problem with random.choice() is you can get the same color on successive calls which is what you don't want:

>>> import random
>>> COLORS = ['red', 'blue', 'green', 'yellow', 'black', 'pink', 'gold', 'violet', 'orange', 'magenta', 'cyan']
>>> for _ in range(10):
...     print(random.choice(COLORS))
... 
green
pink
red
black
violet
orange
orange
violet
yellow
yellow
>>> 

Using random.shuffle() in combination with itertools.cycle() gives you a randomized sequence of colors that repeats from which you can pluck unlike colors one after another:

import turtle
import random
import itertools

COLORS = ['red', 'blue', 'green', 'yellow', 'black', 'pink', 'gold', 'violet', 'orange', 'magenta', 'cyan']

def random_color(iterator=[]):  # intentional dangerous default value
    if not iterator:  # empty container
        colors = COLORS
        random.shuffle(colors)
        iterator.append(itertools.cycle(colors))

    return next(iterator[0])

def square(length, x, y):
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()

    while length >= 10:
        color = random_color()  # change color after each square
        turtle.color(color)

        turtle.begin_fill()

        for _ in range(4):
            turtle.forward(length)
            turtle.right(90)

        turtle.end_fill()

        length -= 10

square(200, -100, 100)

turtle.done()

CS 115 Lab 4, Part B: Draw a grid of colored squares, Python, out of the box, comes with many useful modules. For example, you use the random module to generate random numbers and subsequently, random colors  In this tutorial we're going to talk about that how to get a random color in python programming language by using randint function from random module.

Draw Color Filled Shapes in Turtle - Python, turtle is an inbuilt module in python. It provides drawing using a screen (​cardboard) and turtle (pen). To draw something on the screen, we need to move the turtle. Learn how to draw 4 different squares using 4 different snippets of Python code. You will make use of Python's Turtle module to help draw these shapes.

Python Turtle Tutorial - Shapes and Fills, The following program will randomly draw shapes on the screen. import turtle import random colors = ["red"  How to draw square and rectangle in Python Turtle? Two functions that are useful for us for drawing square and rectangle are- forward() and left(). Before we draw any of the shapes, we must know the basic properties of them. Let's start with a square. All the sides of a square are equal. And the angle between two adjacent sides is 90°.
