Special Topic Sharing on the Turtle Module in Python – Part 4

The module is a drawing library based on Tkinter, designed specifically for beginners. It simulates a “turtle” moving on the screen to draw graphics. It is simple and intuitive, making it ideal for learning programming fundamentals and graphic drawing concepts.

Basic Concepts

• Imagine a turtle with a pen on the screen, which you can control in terms of movement direction, speed, and pen state.
• As the turtle moves, the pen leaves a trail on the screen, forming various shapes.

Common Functions

1. Basic Movement:

• <span class="language-plaintext">forward(distance)</span> / <span class="language-plaintext">fd(distance)</span>: Move forward by the specified distance.
• <span class="language-plaintext">backward(distance)</span> / <span class="language-plaintext">bk(distance)</span>: Move backward by the specified distance.
• <span class="language-plaintext">right(angle)</span> / <span class="language-plaintext">rt(angle)</span>: Rotate right by the specified angle.
• <span class="language-plaintext">left(angle)</span> / <span class="language-plaintext">lt(angle)</span>: Rotate left by the specified angle.

• <span class="language-plaintext">penup()</span> / <span class="language-plaintext">pu()</span>: Lift the pen, moving without leaving a trail.
• <span class="language-plaintext">pendown()</span> / <span class="language-plaintext">pd()</span>: Lower the pen, moving while leaving a trail.
