python十六进制值自定义颜色七段数码绘出

可以使用Python的Turtle库来绘制七段数码管，并使用tkinter中的colorchooser模块来选择自定义颜色。

下面是一个示例代码，它将十六进制值转换为RGB值，并将其用作七段数码管的颜色。

import turtle
import tkinter.colorchooser as cc

# 将十六进制颜色转换为RGB
def hex_to_rgb(hex_value):
    r = int(hex_value[0:2], 16)
    g = int(hex_value[2:4], 16)
    b = int(hex_value[4:6], 16)
    return (r, g, b)

# 绘制七段数码管
def draw_digit(segment_length, color):
    turtle.color(color)
    turtle.pensize(10)
    turtle.penup()
    turtle.goto(0, 0)
    turtle.pendown()
    turtle.forward(segment_length)
    turtle.right(90)
    turtle.forward(segment_length)
    turtle.right(90)
    turtle.forward(segment_length)
    turtle.left(90)
    turtle.forward(segment_length)
    turtle.left(90)
    turtle.forward(segment_length)
    turtle.left(90)
    turtle.forward(segment_length*2)
    turtle.left(90)
    turtle.forward(segment_length)
    turtle.left(90)
    turtle.forward(segment_length)
    turtle.left(90)
    turtle.forward(segment_length)

# 选择自定义颜色
def choose_color():
    color = cc.askcolor()[1]
    return hex_to_rgb(color)

# 初始化Turtle
turtle.speed(0)
turtle.hideturtle()

# 输入十六进制颜色值
hex_value = input("请输入十六进制颜色值：")

# 将十六进制颜色转换为RGB
color = hex_to_rgb(hex_value)

# 绘制数字0-9
segment_length = 50
turtle.penup()
turtle.goto(-300, 0)
turtle.pendown()
for i in range(10):
    draw_digit(segment_length, color)
    turtle.penup()
    turtle.forward(segment_length*2)
    turtle.pendown()

# 点击选择自定义颜色
turtle.penup()
turtle.goto(0, -100)
turtle.pendown()
turtle.write("点击选择自定义颜色", font=("Arial", 16, "bold"))
turtle.penup()
turtle.goto(0, -150)
turtle.pendown()
turtle.write("(按ESC键结束)", font=("Arial", 12))
turtle.penup()
turtle.goto(0, -200)
turtle.pendown()

while True:
    turtle.color("black")
    turtle.write(hex(color[0])[2:].zfill(2).upper() + ":" + hex(color[1])[2:].zfill(2).upper() + ":" + hex(color[2])[2:].zfill(2).upper(), align="center", font=("Arial", 16, "bold"))
    turtle.penup()
    turtle.goto(0, -250)
    turtle.pendown()
    turtle.write("0", font=("Arial", 16, "bold"))
    turtle.penup()
    turtle.goto(0, -50)
    turtle.pendown()
    turtle.write("9", font=("Arial", 16, "bold"))
    turtle.penup()
    turtle.goto(0, -200)
    turtle.pendown()
    turtle.onclick(choose_color)
    turtle.onkey(lambda: turtle.bye(), "Escape")
    turtle.listen()
    color = choose_color()
    turtle.clear()

该程序将在Turtle窗口中显示0-9的七段数码管，并允许用户选择自定义颜色。按ESC键可结束程序。
