常年奋斗在编码一线的同学，应该都深有体会，工作久了，很多项目文件、技术资料，设计文档，安装包等等一堆一堆的工作目录分散在各个磁盘中，需要用到的时候，频繁的在各个目录中切换，每次都得用资源浏览器打开，还得点多次鼠标才能找到，或者有些如Apache或者tomcat等服务又需要用命令行启动，如果文件目录层次比较深的话，每次重复下列动作：
开发运行->cmd->c:\Documents and Settings\Administrator>D:
D:>cd mycode
D:>MyCode>cd python
D:>MyCode>Python>Practise>... 反反复复的重复动作真的是太烦了，自己动手丰衣足食，还是用代码自己来写一段快速定位或切换工作目录的小工具，像工具软件一样点一下就直接打开，岂不是省去敲打那些无聊的cd命令，ok，因为已经凌晨了，突然来了兴致即兴发挥，实在搞不完，这一篇写把总体思路及几个关键的核心代码实现掉，下一篇完成所有功能总体思路：
1.软件中可自定义常用工作目录或文件的配置项
2.选择某一工作目录项可打开命令行，路径直接指向到指定的文件夹处
3.选择某一工作目录项可打开资源浏览器，路径直接指向到指定的文件夹处
4.选择某一文件项可直接打开执行
5.使用python + Qt实现图形化操作界面(基于托盘图标)的工具软件
此篇实现前四个核心功能需求
1.使用python ConfigParser实现可配置项
代码：
class ConfigItem(object):
2 def __init__(self,category,caption,path,icon,command, explorer, execute):
3 self.category = category
4 self.caption = caption
5 self.path = path
6 self.icon = icon
7 self.command = command
8 self.explorer = explorer
9 self.execute = execute
10
11 def readConfigItems(file,sect=None,key=None):
12 if not os.path.isfile(file):
13 raise Exception("FileNotFound")
14 cf = ConfigParser.ConfigParser()
15 cf.read(file)
16 sections = cf.items("sections")
17
18 if sect is None and key is None:
19 l = []
20 for name,key in sections:
21 i = ConfigItem(
22 category= cf.get(key,"category"),
23 caption=cf.get(key,"caption"),
24 path=cf.get(key,"path"),
25 icon=cf.get(key,"icon"),
26 command=cf.getboolean(key,"command"),
27 explorer=cf.getboolean(key,"explorer"),
28 execute=cf.getboolean(key,"execute")
29 )
30 l.append(i)
31 return l
32 return cf.get(sect,key)
33
34 def addConfigItem(file,item):
35 config = ConfigParser.RawConfigParser()
36 if not os.path.isfile(file):
37 raise Exception("FileNotFound")
38 config = ConfigParser.ConfigParser()
39 config.read(file)
40 sections = config.items("sections")
41 new_section = "section" + str(len(sections)+1)
42 config.set("sections",new_section,new_section)
43 config.add_section(new_section)
44 config.set(new_section, 'category', item.category)
45 config.set(new_section, 'caption', item.caption)
46 config.set(new_section, 'path', item.path)
47 config.set(new_section, 'icon', item.icon)
48 config.set(new_section, 'command',item.command)
49 config.set(new_section, 'explorer', item.explorer)
50 config.set(new_section, 'execute', item.execute)
51 # Writing our configuration file to 'example.cfg'
52 with open(file, 'wb') as configfile:
53 config.write(configfile)
54
55
56 if __name__ == "__main__":
57 #os.execvp(file)
58 #openCommand(r"D:MyCodePythonPratices")
59 #openExplorer(r"D:MyCodePythonPratices")
60 item = ConfigItem(
61 category= "3",
62 caption="test",
63 path=1,
64 icon=1,
65 command=True,
66 explorer=True,
67 execute=True
68 )
69 addConfigItem("d:\conf.conf", item)
70 print readConfigItems("d:\conf.conf")配置文件格式：
[sections] section2 = section2 section1 = section1 [section2] category = 1 execute = False explorer = True caption = 工作目录 command = True path = 1 icon = 1 [section1] category = 工作目录 execute = True explorer = True caption = Python练习代码 command = True path = 1 icon = 1
2.使用命令行、资源浏览器打开指定文件夹目录或直接执行可执行文件
