Beginners Guide: Use the 'TURTLE' Library in Python to draw graphics

Beginners Guide: Use the 'TURTLE' Library in Python to draw graphics In Python, you can use the 'TURTLE' library to draw a variety of graphics.This library makes the drawing graphic very simple and suitable for beginners.This guide will introduce you how to use the 'TURTLE' library to draw graphics and provide a complete programming code and related configuration description. Installation and configuration: 1. First, make sure that your computer has been installed on the Python interpreter.You can download and install python from the official website (https://www.python.org). 2. After the installation is completed, enter the following command in the command line interface to check whether the Python is correctly installed: python --version 3. In Python, the ‘TURTLE’ library is installed by default, so you do n’t need to install it.You only need to import the 'TURTLE' library to start using it. Write the drawing code: Now let's write a simple Python program to draw a square: python import turtle # 创 创 创 canvas = turtle.Screen() Canvas.Title ("Drawing Example") # 创 创 创 pen = turtle.Turtle() # Set the color and movement speed of the brush pen.color("blue") pen.speed(1) # Draw a square for _ in range(4): pen.forward(100) pen.right(90) # Turn off the canvas canvas.mainloop() This program uses the 'TURTLE' library to create a canvas called Canvas and create a brush called Pen.The color of the brush is then set to blue and the movement speed is set to 1.Next, a square is drawn with a for loop.Finally, the canvas were turned off by calling the method of calling `canvas.mainloop ()`. Running program: Save the above code into a file (such as `Square.py`), and then run the following command in the command line interface to execute the program: python square.py You will see a blue -square drawing window pop up. Explore more functions: The 'TURTLE' library can not only draw a square, but also draw other shapes, fill colors, and set brush width.Here are some commonly used methods: -` Pen.Forward (Distance) `: Move the specified distance forward -` Pen.backWard (Distance) `: Move the specified distance backwards -` Pen.right (Angle) `: Rotate the specified angle to the right -` Pen.left (Angle) `: Rotate the specified angle to the left -` Pen.color (color_name) `: Set the color of the brush -Pen.pensize (width) `: Set the width of the brush -Pen.fillcolor (color_name) `: Set the fill color -Pen.begin_fill () `: Start filling the graphic -` Pen.end_fill () `: End the filling graphics -` Pen.circle (Radius) `: Draw a circle centered on the current position of the brush By using these methods, you can create a variety of graphics. Summarize: Use Python's "TURTLE" library to easily draw graphics.This guide provides a simple example to help you get started, and also introduces some commonly used methods.You can explore more functions as needed and draw beautiful graphics according to your creativity.Enjoy the fun of python drawing!
