用Python写一个计算器GUI程序

使用Python实现一个计算器GUI非常容易。最简单的方法是使用Tkinter库，它提供了一些基本的GUI元素，如按钮，文本框，标签等，来创建简单的图形用户界面。可以使用这些GUI元素来创建一个计算器，用户可以输入数字，然后选择加减乘除等运算符，最后点击一个按钮来计算结果。

请用Python写一个计算器GUI程序，并给出代码

可以使用Python的tkinter模块来编写一个计算器GUI程序。下面是一个示例代码：from tkinter import *root = Tk()root.title("Calculator")
root.geometry('400x400')text_input = StringVar()
operator = ""def click_button(number):
global operator
operator = operator + str(number)
text_input.set(operator)def clear_button():
global operator
operator = ""
text_input.set("")def equal_button():
global operator
sumup = str(eval(operator))
text_input.set(sumup)
operator = ""text_display = Entry(root, font=('arial', 20, 'bold'), textvariable=text_input, bd=30, insertwidth=4, bg="powder blue",
justify='right').grid(columnspan=4)button1 = Button(root, padx=16, pady=16, bd=8, fg="black", font=('arial', 20, 'bold'), text="1", bg="powder blue",
command=lambda: click_button(1)).grid(row=1, column=0)button2 = Button(root, padx=16, pady=16, bd=8, fg="black", font=('arial', 20, 'bold'), text="2", bg="powder blue",

用 Python 实现的简单计算器 GUI 程序的示例代码，只有四个数字

以下是用 Python 和 Tkinter 实现的简单计算器 GUI 程序示例代码，仅包括四个数字：

import tkinter as tk

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

        self.result = tk.Label(master, text="0", width=12, relief="sunken")
        self.result.grid(row=0, column=0, columnspan=4)

        self.create_button("7", 1, 0)
        self.create_button("8", 1, 1)
        self.create_button("9", 1, 2)
        self.create_button("+", 1, 3)

        self.create_button("4", 2, 0)
        self.create_button("5", 2, 1)
        self.create_button("6", 2, 2)
        self.create_button("-", 2, 3)

        self.create_button("1", 3, 0)
        self.create_button("2", 3, 1)
        self.create_button("3", 3, 2)
        self.create_button("*", 3, 3)

        self.create_button("0", 4, 0)
        self.create_button(".", 4, 1)
        self.create_button("C", 4, 2)
        self.create_button("/", 4, 3)

        self.create_button("=", 5, 0, columnspan=4)

    def create_button(self, text, row, column, columnspan=1):
        button = tk.Button(self.master, text=text, width=3, command=lambda: self.update_result(text))
        button.grid(row=row, column=column, columnspan=columnspan)

    def update_result(self, text):
        if text == "C":
            self.result.config(text="0")
        elif text == "=":
            try:
                self.result.config(text=str(eval(self.result.cget("text"))))
            except SyntaxError:
                self.result.config(text="Error")
        elif self.result.cget("text") == "0":
            self.result.config(text=text)
        else:
            self.result.config(text=self.result.cget("text") + text)

root = tk.Tk()
calculator = Calculator(root)
root.mainloop()

这个简单的计算器 GUI 程序包括一个标签，用于显示计算结果，以及多个按钮，用于输入数字和运算符，支持加、减、乘、除、小数点和清零操作。
