代码如下，只要再加上按键绑定事件函数，计算器既可使用了。
import tkinter as tk
from tkinter.ttk import Separator,Button
if __name__ == '__main__':
Buttons = [['%','CE','C','←'],
['1/x','x²','√x','÷'],
['7', '8', '9', 'x'],
['4', '5', '6', '-'],
['1', '2', '3', '+'],
['±', '0', '.', '=']]
root = tk.Tk()
root.title("计算器")
Separator(root).grid(row=0, column=0, columnspan=4, pady=2)
exp = tk.Label(root, text='', anchor='e', width=42)
exp.grid(row=1, column=0, columnspan=4, padx=6, pady=2)
frm = tk.Frame(root, borderwidth=1, relief="ridge", bg='black')
frm.grid(row=2, column=0, columnspan=4)
res = tk.Label(frm, text='0', font=('微软雅黑',16), width=30, anchor='e', bg='white', padx=5, pady=12)
res.grid(padx=1, pady=1)
Separator(root).grid(row=3, column=0, columnspan=4, pady=2)
for row, Row in enumerate(Buttons):
for col, btn in enumerate(Row):
Button(root, text=btn, width=8, padding=(0, 12)).grid(row=row+4, column=col, padx=4, pady=3)
Separator(root).grid(row=10, column=0, columnspan=4, pady=2)
root.mainloop()代码最关键的就是只用一个双重循环就把24个按键一次搞定：
for row, Row in enumerate(Buttons):
for col, btn in enumerate(Row):
Button(root, text=btn, width=8, padding=(0, 12)).grid(row=row+4, column=col, padx=4, pady=3)除了主角Button控件外，还有三个配角控件：Label、Separator以及Frame
Separator(root).grid(row=0, column=0, columnspan=4, pady=2)
exp = tk.Label(root, text='', anchor='e', width=42)
exp.grid(row=1, column=0, columnspan=4, padx=6, pady=2)
frm = tk.Frame(root, borderwidth=1, relief="ridge", bg='black')
frm.grid(row=2, column=0, columnspan=4)
res = tk.Label(frm, text='0', font=('微软雅黑',16), width=30, anchor='e', bg='white', padx=5, pady=12)
res.grid(padx=1, pady=1)
Separator(root).grid(row=3, column=0, columnspan=4, pady=2)Separator隔开控件用，Frame摆放显示结果的Label标签，Label的原版帮助如下：

|
| bind(self, sequence=None, func=None, add=None)
| Bind to this widget at event SEQUENCE a call to function FUNC.
|
| SEQUENCE is a string of concatenated event
| patterns. An event pattern is of the form
| <MODIFIER-MODIFIER-TYPE-DETAIL> where MODIFIER is one
| of Control, Mod2, M2, Shift, Mod3, M3, Lock, Mod4, M4,
| Button1, B1, Mod5, M5 Button2, B2, Meta, M, Button3,

| ButtonRelease and DETAIL is the Keysym for KeyPress and
| KeyRelease. Examples are
| <Control-Button-1> for pressing Control and mouse button 1 or
| <Alt-A> for pressing A and the Alt key (KeyPress can be omitted).
| An event pattern can also be a virtual event of the form
| <<AString>> where AString can be arbitrary. This
| event can be generated by event_generate.
| If events are concatenated they must appear shortly
| after each other.
|
| FUNC will be called if the event sequence occurs with an
| instance of Event as argument. If the return value of FUNC is
| "break" no further bound function is invoked.
|
| An additional boolean parameter ADD specifies whether FUNC will
| be called additionally to the other bound function or whether
| it will replace the previous function.

|
| bind_class(self, className, sequence=None, func=None, add=None)
| Bind to widgets with bindtag CLASSNAME at event
| SEQUENCE a call of function FUNC. An additional

|
| With no argument return the list of all bindtags associated with
