Circle Matrix with Python Turtle (with Solution)

In this simple python turtle project, you are going to draw a 10×10 matrix of connected circles. You can either use nested loops or define a function that draws a line of circles and and call this function in a single loop.

Solution

import turtle

def draw_circle(x,y,r):
    turtle.up()
    turtle.seth(0)
    turtle.goto(x,y-r)
    turtle.down()
    turtle.circle(r)

def draw_a_line_of_circles(x,y,r,n):
    for i in range(n):
        draw_circle(x,y,r)
        x += 2*r
    
turtle.setup(900,900)
turtle.title("Circle Matrix - PythonTurtle.Academy")
turtle.speed(0)
turtle.hideturtle()
y = 300
radius=30
for i in range(10):
    draw_a_line_of_circles(-300,y,radius,10)
    y -= radius*2
