获取十六进制代码/rgb并以tkinter显示颜色

import tkinter as tk

def show_color():
    color_code = entry.get()  # 获取输入的颜色代码
    try:
        if color_code.startswith("#"):
            # 十六进制代码
            rgb = tuple(int(color_code[i:i+2], 16) for i in (1, 3, 5))
        else:
            # RGB值
            rgb = tuple(map(int, color_code.split(",")))
        
        canvas.config(bg='#%02x%02x%02x' % rgb)  # 设置Canvas背景颜色
    except:
        canvas.config(bg='white')  # 输入错误的颜色代码时，显示白色

root = tk.Tk()
root.title("Color Viewer")

# 创建输入框和按钮
entry = tk.Entry(root, width=20)
entry.pack(pady=10)

button = tk.Button(root, text="Show Color", command=show_color)
button.pack(pady=5)

# 创建Canvas组件
canvas = tk.Canvas(root, width=200, height=200)
canvas.pack()

root.mainloop()
