python 计算器实现，包含标准、科学、程序员，带有界面操作的

可以使用Python内置的Tkinter库来实现一个简单的计算器界面，并在其基础上实现标准、科学、程序员计算器功能。下面是一个简单的示例代码：

import tkinter as tk
import math

class Calculator:
    def __init__(self, master):
        self.master = master
        master.title("Calculator")

        # 创建文本框
        self.display = tk.Entry(master, width=35, borderwidth=5)
        self.display.grid(row=0, column=0, columnspan=4, padx=10, pady=10)

        # 按钮
        self.button_1 = tk.Button(master, text="1", padx=40, pady=20, command=lambda: self.button_click(1))

这个计算器实现了标准、科学、程序员三种模式，可以在不同模式下进行数字、运算符、函数的输入和计算，并且使用了Tkinter库创建了一个简单的图形界面。你可以根据需要自定义不同功能的实现。
