Creating many circles with three different colors using for loop

Code Explanation

import turtle as t: This means t will mean turtle from now.

t.shape("arrow"):This code means that the shape of the pen will be an arrow.

t.bgcolor("black"):This code means that the color the of background will be black.

t.color("pink"):The color of the pen will be pink.

t.pensize(width=3):The width of the pen will be 3.

n = 10: Set n to 10.

colors = ["red", "yellow", "blue"]: The colors will be red, yellow, and blue.

for i in range(3):

    t.color(colors[i])

    t.left(120)

    for x in range(n):

        t.circle(100)

        t.left(360/n)

: This means that the code will be repeated 10 times with each color red, yellow and blue. 

For 10 times, the turtle draw a circle that radius is 100 and turn left by 36 degrees.

t.exitonclick(): The final thing that says exit on click means that the app will close when clicked.
