Python也跟大家一起分享了一段時間了，就像開始學C++一樣，天天看著黑乎乎的控制檯。

所以，今天就開始弄一弄Python中的GUI。

首先需要說明的是，Python沒有一個標準的GUI工具包。所以也就是有不少的Python GUI包。

我們今天介紹的就是一個跨平臺的Python GUI開發包 wxpython。

何為wxpython？
wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module (native code) that wraps the popular wxWidgets cross platform GUI library, which is written in C++.

Like Python and wxWidgets, wxPython is Open Source which means that it is free for anyone to use and the source code is available for anyone to look at and modify. Or anyone can contribute fixes or enhancements to the project.

wxPython is a cross-platform toolkit. This means that the same program will run on multiple platforms without modification. Currently supported platforms are 32-bit Microsoft Windows, most Unix or unix-like systems, and Macintosh OS X.

Since the language is Python, wxPython programs are simple, easy to write and easy to understand. Here is an example.

1明確自己的Python版本
例如2.7

這裡需要注意的是，不僅僅要知道自己的Python版本，還是清楚Python是32位還是64位。

大家不要有誤區就行，只要知道64位系統上既可以安裝32位的程式也可以安裝64位的程式。

這麼多廢話的意思就是不要弄錯了，python2.7為32位，就要下載：
wxPython3.0-win32-py27 32-bit Python 2.7

下載完成就是下一步 下一步 直到完成了。

3第一個GUI應用程式
我們用JetBrains PyCharm 3.4.1編寫程式碼：

import wx
app = wx.App()
win = wx.Frame(None)
btn = wx.Button(win)
win.Show()
app.MainLoop()

執行結果如下：

加點酌料

import wx
app = wx.App()
win = wx.Frame(None, title = 'Simple Editor', size = (410, 335))
win.Show()

loadButton = wx.Button(win, label = 'Open', pos = (235, 5), size = (80, 25))

saveButton = wx.Button(win, label = 'Save', pos = (315, 5), size = (80, 25))

filename = wx.TextCtrl(win, pos=(5, 5), size = (210, 25))

#contents = wx.TextCtrl(win, pos=(5, 35), size = (390, 260), style=wx.TE_MULTILINE | wx.HScrolledWindow)

app.MainLoop()
