python tkinter 最简洁的计算器按钮排列

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：

| bell(self, displayof=0)

| Ring a display’s bell.

|

| 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

| where MODIFIER is one

| of Control, Mod2, M2, Shift, Mod3, M3, Lock, Mod4, M4,

| Button1, B1, Mod5, M5 Button2, B2, Meta, M, Button3,

| for pressing Control and mouse button 1 or

| for pressing A and the Alt key (KeyPress can be omitted).

| An event pattern can also be a virtual event of the form

| 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 will return an identifier to allow deletion of the bound function with

| unbind without memory leak.

| it will replace the previous function. See bind for the return value.

|

| 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

| boolean parameter ADD specifies whether FUNC will be

| called additionally to the other bound function or

| the return value.

|

| bindtags(self, tagList=None)

| Set or get the list of bindtags for this widget.

|

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