通过turtle库函数绘制七段数码管形式

可以使用turtle库中的函数来绘制七段数码管形式。以下是一个示例代码：

import turtle

# 定义绘制线段的函数
def draw_line(length):
    turtle.pendown()
    turtle.forward(length)
    turtle.penup()

# 定义绘制数字0的函数
def draw_0():
    draw_line(50)
    turtle.right(90)
    draw_line(100)
    turtle.right(90)
    draw_line(50)
    turtle.right(90)
    draw_line(100)
    turtle.penup()

# 定义绘制数字1的函数
def draw_1():
    turtle.right(90)
    draw_line(100)
    turtle.penup()
    turtle.right(180)
    turtle.forward(50)
    turtle.right(90)
    turtle.forward(100)
    turtle.right(180)

# 定义绘制数字2的函数
def draw_2():
    draw_line(50)
    turtle.right(90)
    draw_line(50)
    turtle.right(45)
    draw_line(70.7)
    turtle.left(135)
    draw_line(50)
    turtle.penup()
    turtle.left(90)
    turtle.forward(50)
    turtle.right(90)

# 定义绘制数字3的函数
def draw_3():
    draw_line(50)
    turtle.right(135)
    draw_line(70.7)
    turtle.left(135)
    draw_line(50)
    turtle.right(135)
    draw_line(70.7)
    turtle.penup()

# 定义绘制数字4的函数
def draw_4():
    turtle.right(90)
    draw_line(50)
    turtle.left(90)
    draw_line(50)
    turtle.right(90)
    draw_line(50)
    turtle.right(180)
    draw_line(100)
    turtle.penup()
    turtle.right(90)
    turtle.forward(50)
    turtle.right(90)

# 定义绘制数字5的函数
def draw_5():
    turtle.right(90)
    draw_line(50)
    turtle.left(90)
    draw_line(50)
    turtle.left(45)
    draw_line(70.7)
    turtle.right(135)
    draw_line(50)
    turtle.penup()
    turtle.right(90)
    turtle.forward(50)
    turtle.right(90)

# 定义绘制数字6的函数
def draw_6():
    draw_line(50)
    turtle.left(90)
    draw_line(100)
    turtle.right(90)
    draw_line(50)
    turtle.right(90)
    draw_line(50)
    turtle.right(90)
    draw_line(50)
    turtle.penup()
    turtle.right(90)
    turtle.forward(50)
    turtle.right(90)

# 定义绘制数字7的函数
def draw_7():
    turtle.right(90)
    draw_line(100)
    turtle.left(135)
    draw_line(70.7)
    turtle.penup()
    turtle.right(45)
    turtle.forward(50)
    turtle.right(90)

# 定义绘制数字8的函数
def draw_8():
    draw_line(50)
    turtle.right(90)
    draw_line(100)
    turtle.right(90)
    draw_line(50)
    turtle.right(90)
    draw_line(100)
    turtle.penup()
    turtle.right(90)
    turtle.forward(50)
    turtle.right(90)

# 定义绘制数字9的函数
def draw_9():
    draw_line(50)
    turtle.right(90)
    draw_line(50)
    turtle.right(90)
    draw_line(50)
    turtle.right(90)
    draw_line(100)
    turtle.penup()
    turtle.right(90)
    turtle.forward(50)
    turtle.right(90)

# 设置初始位置和角度
turtle.penup()
turtle.goto(-200, 0)
turtle.setheading(0)

# 绘制数字7段数码管
draw_1()
turtle.forward(100)
draw_2()
turtle.forward(100)
draw_3()
turtle.goto(-200, -150)
draw_4()
turtle.forward(100)
draw_5()
turtle.forward(100)
draw_6()
turtle.goto(-200, -300)
draw_7()
turtle.forward(100)
draw_8()
turtle.forward(100)
draw_9()

# 隐藏海龟
turtle.hideturtle()

# 显示窗口
turtle.mainloop()

在上面的代码中，我们定义了绘制线段的函数和绘制数字0到9的函数。然后，我们使用这些函数来绘制数字7段数码管。最后，我们隐藏了海龟，并使用`mainloop`函数来显示窗口。运行代码后，可以看到绘制的七段数码管形式。
