下面是用python TK库写的同样程序，对比一下代码量

import tkinter as tk
import mathdef calculate_area():try:radius = float(radius_entry.get())area = math.pi * radius ** 2area_label.config(text=f"{area}")except ValueError:area_label.config(text="请输入有效的半径值")def clear_fields():radius_entry.delete(0, tk.END)area_label.config(text="")root = tk.Tk()
root.title("圆面积计算程序")
root.geometry("300x200")
root.configure(bg="purple")# 设置标题
title_label = tk.Label(root, text="计算圆的面积", font=("Arial", 16), bg="purple", fg="white")
title_label.pack(pady=10)# 半径输入部分
radius_frame = tk.Frame(root, bg="purple")
radius_frame.pack()radius_label = tk.Label(radius_frame, text="半径：", bg="purple", fg="white")
radius_label.pack(side=tk.LEFT)radius_entry = tk.Entry(radius_frame, width=10)
radius_entry.pack(side=tk.LEFT)# 面积显示部分
area_frame = tk.Frame(root, bg="purple")
area_frame.pack()area_label_text = tk.Label(area_frame, text="面积：", bg="purple", fg="white")
area_label_text.pack(side=tk.LEFT)area_label = tk.Label(area_frame, text="", width=15)
area_label.pack(side=tk.LEFT)# 按钮部分
button_frame = tk.Frame(root, bg="purple")
button_frame.pack(pady=10)calculate_button = tk.Button(button_frame, text="计算", command=calculate_area)
calculate_button.pack(side=tk.LEFT, padx=5)clear_button = tk.Button(button_frame, text="清空", command=clear_fields)
clear_button.pack(side=tk.LEFT, padx=5)exit_button = tk.Button(button_frame, text="退出", command=root.quit)
exit_button.pack(side=tk.LEFT, padx=5)root.mainloop()
