python ConfigParser 的小技巧

$ cat format.conf

[DEFAULT]

conn_str = %(dbn)s://%(user)s:%(pw)s@%(host)s:%(port)s/%(db)s

dbn = mysql

user = root

host=localhost

port = 3306

[db1]

user = aaa

pw=ppp

db=example

[db2]

host=192.168.0.110

pw=www

db=example

 

print conf.get('db1', 'conn_str')

print conf.get('db2', 'conn_str')

這樣就能夠很方便的獲得 db1和db2的鏈接串
