python简易计算器窗口

好的，以下是一个简单的 Python 计算器窗口的示例代码，你可以参考它进行修改和扩展:

from tkinter import *

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

        self.screen = Text(master, state='disabled', width=30, height=3,background="white", foreground="black")
        self.screen.grid(row=0, column=0, columnspan=4, padx=5, pady=5)
        self.screen.configure(state='normal')

        # 创建按钮并放置在网格中
        b1 = self.create_button(7)
        b2 = self.create_button(8)
        b3 = self.create_button(9)
        b4 = self.create_button(u"\u232B",None)
        b5 = self.create_button(4)
        b6 = self.create_button(5)
        b7 = self.create_button(6)
        b8 = self.create_button(u"\u00F7")
        b9 = self.create_button(1)
        b10 = self.create_button(2)
        b11 = self.create_button(3)
        b12 = self.create_button('*')
        b13 = self.create_button('.')
        b14 = self.create_button(0)
        b15 = self.create_button('+')
        b16 = self.create_button('-')
        b17 = self.create_button('=',None, 34)

        # 存储按钮在列表中，以便于更改按钮颜色
        self.buttons = [b1, b2, b3, b4, b5, b6, b7, b8, b9, b10, b11, b12, b13, b14, b15, b16, b17]

        # 创建 Clear 按钮并放置在网格中
        clear_button = Button(master, text="Clear", width=14, height=2, command=self.clear)
        clear_button.grid(row=1, column=3, padx=5, pady=5)

    def create_button(self, val, write=True, width=7):
        # 创建按钮的函数
        return Button(self.master, text=val, width=width, command=lambda: self.click(val,write))

    def click(self, text, write):
        # 处理单击事件，将文本插入显示屏
        if write == None:
            # 处理计算器中的特殊按键
            if text == '=' and self.screen.get('1.0', END) != '':
                # 尝试计算表达式字符串
                try:
                    result = eval(self.screen.get('1.0', END))
                    self.clear()
                    self.screen.insert(END, result)
                except:
                    self.clear()
                    self.screen.insert(END, '错误')
            elif text == u"\u232B":
                # 处理退格键
                current = self.screen.get('1.0', END)
                self.clear()
                self.screen.insert(END, current[:-2])
                
        else:
            # 处理数字和运算符
            self.screen.insert(END, text)

    def clear(self):
        # 清空显示屏
        self.screen.configure(state='normal')
        self.screen.delete('1.0', END)

root = Tk()
my_gui = Calculator(root)
root.mainloop()

这个简易计算器窗口使用 Tkinter 模块创建，包含了数字、运算符和特殊按键。你可以通过修改按钮的标签和单击事件来扩展它的功能。
