用python内置的GUI库tkinter编写计算器

前言：使用Python内置编写GUI界面程序的库来写一个简单的计算器。
源代码：
ps：code这东西不好解释，请看注释自己调试运行。

from tkinter import *
import tkinter as tk
window = tk.Tk()
window.title('Bin计算器')
sizable(width=0, height=0)  # 禁止使用鼠标缩放常开
### 获取屏幕分辨率然后使其窗口的时候居中
x_screen=window.winfo_screenwidth()-300
y_sreeen=window.winfo_screenheight()-350
x=int(x_screen/2)
y=int(y_sreeen/2)
ry(f'300x350+{x}+{y}')
# window icon  ps：如果复制代码记得修改成自己的图片路径！
window.iconphoto(False, tk.PhotoImage(file='bin.png'))# text box
text = Text(window, width=40, height=6, undo=True, autoseparators=False)
text.pack()# ******* button_function *******

结果：
ps：有些表达式错误导致异常的问题这里没有继续优化不过本身不影响使用；只能进行简单的加减乘除运算。
