How to use the circle function in Python?

The circle function in Python is used for drawing circles. It is usually used by importing the turtle module.

Here is an example of drawing a circle using the circle function:

import turtle

# 创建一个画布
canvas = turtle.Screen()

# 创建一个画笔
paintbrush = turtle.Turtle()

# 设置画笔的形状为圆形
paintbrush.shape("circle")

# 设置画笔的颜色
paintbrush.color("red")

# 设置画笔的速度
paintbrush.speed(1)

# 绘制一个半径为100的红色圆形
paintbrush.circle(100)

# 结束绘制
turtle.done()

In this example, we first create a canvas and a brush. Next, we set the brush’s shape to be a circle, color to be red, and speed to be 1. Finally, we use the circle function to draw a circle with a radius of 100.

You can adjust the radius, color, speed, and other parameters of the circle as needed to achieve different effects.
