二、安装
　　参考官方网站：http://www.wxpython.org/download.php

三、DEMO
　　本demo是一个简单的记事本软件，可以打开文件，修改并保存。



import wx
app = wx.App()
win = wx.Frame(
None,
title="simple editor",
size=(410, 335))
bkg = wx.Panel(win)

def openFile(evt):
dlg = wx.FileDialog(
win,
"Open",
"",
"",
"All files (*.*)|*.*",
wx.FD_OPEN | wx.FD_FILE_MUST_EXIST)
filepath = ''
if dlg.ShowModal() == wx.ID_OK:
filepath = dlg.GetPath()
else:
return
filename.SetValue(filepath)
fopen = open(filepath)
fcontent = fopen.read()
contents.SetValue(fcontent)
fopen.close()

def saveFile(evt):
fcontent = contents.GetValue()
fopen = open(filename.GetValue(), 'w')
fopen.write(fcontent)
fopen.close()
openBtn = wx.Button(bkg, label='open')
openBtn.Bind(wx.EVT_BUTTON, openFile)
saveBtn = wx.Button(bkg, label='save')
saveBtn.Bind(wx.EVT_BUTTON, saveFile)
filename = wx.TextCtrl(bkg, style=wx.TE_READONLY)
contents = wx.TextCtrl(bkg, style=wx.TE_MULTILINE)
hbox = wx.BoxSizer()
hbox.Add(openBtn, proportion=0, flag=wx.LEFT | wx.ALL, border=5)
hbox.Add(filename, proportion=1, flag=wx.EXPAND | wx.TOP | wx.BOTTOM, border=5)
hbox.Add(saveBtn, proportion=0, flag=wx.LEFT | wx.ALL, border=5)
bbox = wx.BoxSizer(wx.VERTICAL)
bbox.Add(hbox, proportion=0, flag=wx.EXPAND | wx.ALL)
bbox.Add(
contents,
proportion=1,
flag=wx.EXPAND | wx.LEFT | wx.BOTTOM | wx.RIGHT,
border=5)
bkg.SetSizer(bbox)
win.Show()
app.MainLoop()
　　运行效果：
