配置文件内容：
[plain] view plain copy
[db]
db_host=127.0.0.1
db_port=3306
db_user=root
db_pass=password
[concurrent]
thread=10
processor=20
如果遵循以上格式，那么就可以用python的ConfigParser模块。
[python] view plain copy
#!/usr/bin/python
# Filename: parse_module.py
import ConfigParser
filename = 'my.conf'
parse = ConfigParser.ConfigParser()
parse.read(filename)
sections = parse.sections()
for i in sections:
options = parse.options(i)
values = parse.items(i)
print "Section is %s " % i
print "Options are %s " % options
print "Values are %s " % values
输出：
[plain] view plain copy
Section is db
Options are ['db_host', 'db_port', 'db_user', 'db_pass']
Values are [('db_host', '127.0.0.1'), ('db_port', '3306'), ('db_user', 'root'), ('db_pass', 'password')]
Section is concurrent
Options are ['thread', 'processor']
Values are [('thread', '10'), ('processor', '20')]
但是如果配置文件中，parameter选项中含有[],则无法用此模块进行解析。。因此当试用python作为开发语言时，配置文件的格式可以选择符合configparser模块的格式。。。
