很多软件都有配置文件,今天介绍一下python ConfigParser模块解析配置文件的使用方法
测试配置文件test.conf内容如下:
代码如下:
[first]
w = 2
v: 3
c =11-3
[first]
w = 2
v: 3
c =11-3
[second]
sw=4
test: hello
测试配置文件中有两个区域,first和second,另外故意添加一些空格、换行。
下面解析:
代码如下:
>>> import ConfigParser
>>> conf=ConfigParser.ConfigParser()
>>> conf.read('test.conf')
['test.conf']
>>> conf.sections() #获得所有区域
['first', 'second']
>>> for sn in conf.sections():
...
print
conf.options(sn)
#打印出每个区域的所有属性
...
['w', 'v', 'c']
['sw', 'test']
>>> import ConfigParser
>>> conf=ConfigParser.ConfigParser()
>>> conf.read('test.conf')
['test.conf']
>>> conf.sections()
['first', 'second']
>>> for sn in conf.sections():
...
...
['w', 'v', 'c']
['sw', 'test']
获得每个区域的属性值:
代码如下:
for sn in conf.sections():
print
sn,'-->'
for attr in
conf.options(sn):
print attr,'=',conf.get(sn,attr)
for sn in conf.sections():
输出:
代码如下:
first -->
w = 2
v = 3
c = 11-3
second -->
sw = 4
test = hello
first -->
w = 2
v = 3
c = 11-3
second -->
sw = 4
test = hello
好了,以上就是基本的使用过程,下面是动态的写入配置,
代码如下:
cfd=open('test2.ini','w')
conf=ConfigParser.ConfigParser()
conf.add_section('test')
#add a section
conf.set('test','run','false')
conf.set('test','set',1)
conf.write(cfd)
cfd.close()
cfd=open('test2.ini','w')
conf=ConfigParser.ConfigParser()
conf.add_section('test')
conf.set('test','run','false')
conf.set('test','set',1)
conf.write(cfd)
cfd.close()
上面是向test2.ini写入配置信息。
