绘制太极八卦图Python

你可以使用Python的turtle库来绘制太极八卦图。具体步骤如下：

1. 导入turtle库

import turtle

2. 创建画布和画笔

window = turtle.Screen()
pen = turtle.Turtle()

3. 设置画笔的颜色和大小

pen.color('black')
pen.pensize(3)

4. 绘制圆形和半圆形

# 绘制黑色半圆
pen.begin_fill()
pen.fillcolor('black')
pen.circle(100, 180)
pen.end_fill()

# 绘制白色半圆
pen.begin_fill()
pen.fillcolor('white')
pen.circle(100, -180)
pen.end_fill()

# 绘制黑色小圆
pen.penup()
pen.goto(0, 50)
pen.pendown()
pen.begin_fill()
pen.fillcolor('black')
pen.circle(25)
pen.end_fill()

# 绘制白色小圆
pen.penup()
pen.goto(0, -50)
pen.pendown()
pen.begin_fill()
pen.fillcolor('white')
pen.circle(25)
pen.end_fill()

5. 绘制两个小圆内部的阴阳鱼

# 绘制黑色阴鱼
pen.penup()
pen.goto(0, 25)
pen.pendown()
pen.color('white', 'black')
pen.begin_fill()
pen.circle(-25, 180)
pen.circle(-12.5, -180)
pen.left(90)
pen.forward(50)
pen.end_fill()

# 绘制白色阳鱼
pen.penup()
pen.goto(0, -25)
pen.pendown()
pen.color('black', 'white')
pen.begin_fill()
pen.circle(25, 180)
pen.circle(12.5, -180)
pen.left(90)
pen.forward(-50)
pen.end_fill()

6. 隐藏画笔

pen.hideturtle()

完整代码如下：

import turtle

window = turtle.Screen()
pen = turtle.Turtle()

pen.color('black')
pen.pensize(3)

# 绘制黑色半圆
pen.begin_fill()
pen.fillcolor('black')
pen.circle(100, 180)
pen.end_fill()

# 绘制白色半圆
pen.begin_fill()
pen.fillcolor('white')
pen.circle(100, -180)
pen.end_fill()

# 绘制黑色小圆
pen.penup()
pen.goto(0, 50)
pen.pendown()
pen.begin_fill()
pen.fillcolor('black')
pen.circle(25)
pen.end_fill()

# 绘制白色小圆
pen.penup()
pen.goto(0, -50)
pen.pendown()
pen.begin_fill()
pen.fillcolor('white')
pen.circle(25)
pen.end_fill()

# 绘制黑色阴鱼
pen.penup()
pen.goto(0, 25)
pen.pendown()
pen.color('white', 'black')
pen.begin_fill()
pen.circle(-25, 180)
pen.circle(-12.5, -180)
pen.left(90)
pen.forward(50)
pen.end_fill()

# 绘制白色阳鱼
pen.penup()
pen.goto(0, -25)
pen.pendown()
pen.color('black', 'white')
pen.begin_fill()
pen.circle(25, 180)
pen.circle(12.5, -180)
pen.left(90)
pen.forward(-50)
pen.end_fill()

# 隐藏画笔
pen.hideturtle()

window.mainloop()
