python ConfigParser读取配置文件的例子

[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

[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)

[root@xen-monitor xenscript]# python test.py
sections ['concurrent', 'db']

db: [('db_port', '3306'), ('db_user', 'root'), ('db_host', '127.0.0.1'), ('db_pass', 'password')]
