Getting Started with Python's Turtle Graphics

This tutorial demonstrates how to use Python's built-in turtle module for creating simple graphics. It begins by importing the module and creating a pen object, then shows how to set the pen's speed, color, and size.

import turtle t = turtle.Pen() t.speed(100) t.color("red") t.pensize(40) t.forward(100)

The article explains that the forward function moves the pen forward, while left and right rotate the drawing direction. Example rotation code:

t.right(45) # angle in degrees t.forward(100)

Additional drawing functions are covered: circle(radius) draws a circle, dot() creates a dot, and goto(x, y) moves the pen to a specific coordinate without drawing unless the pen is down. The up() and down() functions control whether movement leaves a trace.

Several complete code snippets illustrate these concepts. A more elaborate example creates a colorful pattern using loops, color fills, and multiple pen movements:

# coding=utf-8 import turtle import time turtle.color("red", "yellow") turtle.begin_fill() for _ in range(50): turtle.forward(200) turtle.left(170) turtle.end_fill() turtle.mainloop()

Another example defines a custom curve function and combines it with pen rotations to produce a complex shape:

import turtle p = turtle.Pen() p.speed(50) def curvemove(): for i in range(200): p.right(1) p.forward(1) p.color('red','pink') p.begin_fill() p.left(140) p.forward(111.65) curvemove() p.left(120) curvemove() p.forward(111.65) p.end_fill()

Throughout the guide, screenshots illustrate the resulting drawings, and a final note encourages readers to explore further by reading the original source.
