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 math

def calculate_area():
    try:
        radius = float(radius_entry.get())
        area = math.pi * radius ** 2
        area_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()
