turtle.dot() function in Python

The turtle.dot() function is used to draw a circular dot with a specified diameter (size) and an optional color. If the size is not provided, Python automatically chooses a default size based on the current pen size (max(pensize+4, 2*pensize)).

Syntax :

turtle.dot(size=None, *color)

Parameters:

Examples

Example 1: Drawing a single dot

import turtle

t = turtle.Turtle()
t.speed(1)

t.forward(100)
t.dot(60, "yellow")   # dot of diameter 60 with yellow color

turtle.done()

Output

Explanation:

• The turtle moves forward 100 units.
• t.dot(60, "yellow") places a filled yellow circle of size 60 at that point.

Example 2: Creating a layered dot pattern

import turtle

turtle.delay(500)
turtle.ht()

turtle.dot(200, "red")
turtle.dot(180, "orange")
turtle.dot(160, "yellow")
turtle.dot(140, "green")
turtle.dot(120, "blue")
turtle.dot(100, "indigo")
turtle.dot(80, "violet")
turtle.dot(60, "white")

turtle.write("GFG", align="center", font=("Verdana", 12, "bold"))

turtle.done()

Output

Explanation:

• dot(size, color) draws multiple dots of different sizes and colors, centered at the same point.
• Dots overlap to form concentric circles.
• turtle.write() adds text "GFG" at the center of the pattern.
