Foreword:

1. You need to introduce the turtle library before starting. If you have not downloaded this library, you can copy the following statement and download it in the PyCharm terminal.

 

pip install turtle

2. Turtle library, this brush is on the horizontal axis x-axis of this window, and the vertical axis y-axis starts from the origin (0, 0), and uses function instructions to move the drawing.

1: Introduce the required libraries before starting

# turtle as t 是将turtle替换为t
import turtle as t
# 随机库
import random
# 引入turtle库中的所有用法
from turtle import *

 2: Set window properties, RGB color properties and drawing dimensions

# 设置窗口大小和背景颜色
t.screensize(800,700,'black')

# RGB默认范围是0~1，通过Screen().colormode设置成0~255
Screen().colormode(255)

# 加快作图数度
t.speed(speed='fastest')
