学了一周的Python，这篇文章算是为这段时间自学做的小总结。
一、Python简介
Python是一门十分优美的脚本语言，如果学过java、c++那入门Python是非常简单的。Python具有丰富和强大的类库。它常被昵称为胶水语言，它能够很轻松的把用其他语言制作的各种模块（尤其是C/C++）轻松地联结在一起。常见的一种应用情形是，使用Python快速生成程序的原型（有时甚至是程序的最终界面），然后对其中有特别要求的部分，用更合适的语言改写。
二、Python版计算器的实现
工具准备：
1. Python2.7
2. wxPython
3. wxGlade界面编辑工具
4. pyCharm
具体配置什么的我就不说了，网上有很多。Python的GUI开发库有很多，这里我们使用wxPython。用wxGlade编辑界面，wxGlade是一款很好用的GUI编辑工具，它最大的优点是能自动生成编辑好的图形界面的代码。
这里主要介绍几点：
wx.TextCtrl（文本输入控件），这个作为计算器的显示屏，点击数字时用AppendText方法将数字添加至文本末尾，要取出数字时用GetValue方法，点击运算符时要将文本框中的数字清空（先存储）用Clear方法然后还有将操作符保存，点击等号后要将第二个操作数存储，然后用int方法将字符串转换为数字，计算后用SetValue方法将结果送入文本框，具体代码如下：
import wx
# begin wxGlade: extracode
# end wxGlade
class MyFrame(wx.Frame):
def __init__(self,*args,**kwds):
# begin wxGlade: MyFrame.__init__
kwds["style"] = wx.DEFAULT_FRAME_STYLE
wx.Frame.__init__(self,**kwds)
self.text_ctrl_1 = wx.TextCtrl(self,-1,"",style=wx.TE_READONLY)
self.button_37 = wx.Button(self,"1")
self.button_38 = wx.Button(self,"2")
self.button_39 = wx.Button(self,"3")
self.button_40 = wx.Button(self,"+")
self.button_41 = wx.Button(self,"4")
self.button_42 = wx.Button(self,"5")
self.button_43 = wx.Button(self,"6")
self.button_44 = wx.Button(self,"-")
self.button_46 = wx.Button(self,"7")
self.button_45 = wx.Button(self,"8")
self.button_47 = wx.Button(self,"9")
self.button_48 = wx.Button(self,"x")
self.button_49 = wx.Button(self,"C")
self.button_50 = wx.Button(self,"0")
self.button_51 = wx.Button(self,"=")
self.button_52 = wx.Button(self,"/")

按钮的ID，名称什么的我基本都是用wxGlade自动生成的。
没有做什么美化，只是为了练练手，给张图：
