python中对于配置文件的读取

配置文件内容

[root@xen-monitor xenscript]# cat test.conf
[db]  
db_host=127.0.0.1  
db_port=3306  
db_user=root  
db_pass=password  
[concurrent]  
thread=10  
processor=20

 

测试脚本
[root@xen-monitor xenscript]# cat test.py
#!/usr/bin/python -O

import ConfigParser
import string, os, sys

cf = ConfigParser.ConfigParser()
cf.read('test.conf')

s = cf.sections()
print "sections",s

o = cf.options("db")  
print 'options:', o  
v = cf.items("db")  
print 'db:', v  
print '-'*60  

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") 

print '*'*80
print "db_host:%s,db_pass:%s,db_user:%s,db_port:%s" % (db_host,db_pass,db_user,db_port)

 

脚本执行结果

[root@xen-monitor xenscript]# python test.py
sections ['concurrent', 'db']
options: ['db_port', 'db_user', 'db_host', 'db_pass']
db: [('db_port', '3306'), ('db_user', 'root'), ('db_host', '127.0.0.1'), ('db_pass', 'password')]
