运维进行时

    在程序中使用配置文件来灵活的配置一些参数是一件很常见的事情，配置文件的解析并不复杂，在python里更是如此，在官方发布的库中就包含有做这件事情的库，那就是ConfigParser，这里简单的做一些介绍。
    ConfigParser解析的配置文件的格式比较象ini的配置文件格式，就是文件中由多个section构成，每个section下又有多个配置项，比如：

    假设上面的配置文件的名字为test.conf。里面包含两个section,一个是db, 另一个是concurrent, db里面还包含有4项，concurrent里面有两项。这里来做做解析：
#-*- encoding: gb2312 -*- import ConfigParser import string, os, sys cf = ConfigParser.ConfigParser() cf.read("test.conf") # 返回所有的section s = cf.sections() print 'section:', s o = cf.options("db") print 'options:', o v = cf.items("db") print 'db:', v print '-'*60 #可以按照类型读取出来 db_host = cf.get("db", "db_host") db_port = cf.getint("db", "db_port") db_user = cf.get("db", "db_user") db_pass = cf.get("db", "db_pass") # 返回的是整型的 threads = cf.getint("concurrent", "thread") processors = cf.getint("concurrent", "processor") print "db_host:", db_host print "db_port:", db_port print "db_user:", db_user print "db_pass:", db_pass print "thread:", threads print "processor:", processors #修改一个值，再写回去 cf.set("db", "db_pass", "zhaowei") cf.write(open("test.conf", "w"))

Hyperlinks
AppSnap displays the website of an application amongst other details. It would be ideal to open the link in the default browser when clicked. Luckily for us, wxPython has a widget just for this.

Let’s create a hyperlink:

# Create hyperlink on an existing panel widget
link = wx.lib.hyperlink.HyperLinkCtrl(parent=panel, pos=(225, 60))

For starters, let’s initialize the link.

# Initialize the hyperlink
link.SetURL(URL=”)
link.SetLabel(label=”)
link.SetToolTipString(tip=”)
