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",
command=lambda: click_button(2)).grid(row=1, column=1)button3 = Button(root, padx=16, pady=16, bd=8, fg="black", font=('arial', 20, 'bold'), text="3", bg="powder blue",

帮我用python写一个带GUI的计算器的程序

好的，这里是一个简单的 Python GUI 计算器程序，使用 tkinter 模块构建：

import tkinter as tk

class Calculator:
    def __init__(self, master):
        self.master = master
        master.title("简单计算器")

        # 创建输入框
        self.entry = tk.Entry(master, width=20, font=('Arial', 16))
        self.entry.grid(row=0, column=0, columnspan=4, padx=5, pady=5)

        # 创建数字按钮
        for i in range(10):
            tk.Button(master, text=str(i), width=5, height=2, command=lambda num=i: self.button_click(str(num))).grid(row=(i//3)+1, column=i%3, padx=5, pady=5)

        # 创建操作符按钮
        tk.Button(master, text='+', width=5, height=2, command=lambda: self.button_click('+')).grid(row=1, column=3, padx=5, pady=5)
        tk.Button(master, text='-', width=5, height=2, command=lambda: self.button_click('-')).grid(row=2, column=3, padx=5, pady=5)
        tk.Button(master, text='*', width=5, height=2, command=lambda: self.button_click('*')).grid(row=3, column=3, padx=5, pady=5)
        tk.Button(master, text='/', width=5, height=2, command=lambda: self.button_click('/')).grid(row=4, column=3, padx=5, pady=5)

        # 创建功能按钮
        tk.Button(master, text='AC', width=5, height=2, command=self.clear_entry).grid(row=1, column=0, padx=5, pady=5)
        tk.Button(master, text='←', width=5, height=2, command=self.delete_entry).grid(row=1, column=1, padx=5, pady=5)
        tk.Button(master, text='=', width=5, height=2, command=self.calculate).grid(row=4, column=2, padx=5, pady=5)
        tk.Button(master, text='.', width=5, height=2, command=lambda: self.button_click('.')).grid(row=4, column=1, padx=5, pady=5)

    # 按钮点击事件
    def button_click(self, num):
        self.entry.insert(tk.END, num)

    # 清空输入框
    def clear_entry(self):
        self.entry.delete(0, tk.END)

    # 删除输入框最后一个字符
    def delete_entry(self):
        self.entry.delete(len(self.entry.get())-1, tk.END)

    # 计算结果
    def calculate(self):
        expression = self.entry.get()
        try:
            result = eval(expression)
            self.entry.delete(0, tk.END)
            self.entry.insert(0, result)
        except:
            self.clear_entry()
            self.entry.insert(0, "Error")

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

这个程序将创建一个简单的 GUI 界面，包括一个输入框和各种数字、操作符、功能按钮。你可以点击按钮输入数字和运算符，也可以点击功能按钮进行清空、删除和计算。程序会根据输入的表达式计算并输出结果，如果出现错误，会在输入框中显示 "Error"。
