用Python写一段带UI界面的计算器程序

你可以使用Python GUI库, 比如 tkinter, PyQt, wxPython等来实现一个带有用户界面的计算器程序.

具体来说, 你需要创建一个界面, 在界面上放置按钮和文本框, 然后编写相应的代码实现计算器的功能.

以下是一个使用tkinter库创建计算器界面的简单代码示例:

import tkinter as tk

root = tk.Tk()
root.title("Calculator")

e = tk.Entry(root, width=35, borderwidth=5)
e.grid(row=0, column=0, columnspan=3, padx=10, pady=10)

def button_click(number):
    current = e.get()
    e.delete(0, tk.END)
    e.insert(0, str(current) + str(number))

def button_clear():
    e.delete(0, tk.END)

def button_add():
    first_number = e.get()
    global f_num
    f_num = int(first_number)
    e.delete(0, tk.END)

def button_equal():
    second_number = e.get()
    e.delete(0, tk.END)
    e.insert(0, f_num + int(second_number))

# Define buttons
button_1 = tk.Button(root, text="1", padx=40, pady=20, command=lambda: button_click(1))
button_2 = tk.Button(root, text="2", padx=40, pady=20, command=lambda: button_click(2))
button_3 = tk.Button(root, text="3", padx=40, pady=20, command=lambda: button_click(3))
button_4 = tk.Button(root, text="4", padx=40, pady=20, command=lambda: button_click(4))
button_5 = tk.Button(root, text="5", padx=40, pady=20, command=lambda: button_click(5))
button_6 = tk.Button(root, text="6", padx=40, pady=20, command=lambda: button_click(6))
button_7 = tk.Button(root, text="7", padx=40, pady=20, command=lambda: button_click(7))
button_8 = tk.Button(root, text="8", padx=40, pady=20, command=lambda: button_click(8))
