执行：

./parse_conf.py test.ini 
main args:2
['concurrent', 'db']
echo of section
section name: concurrent
items:
[('processor', '20'), ('thread', '10')]


concurrent:processor ==> 20
concurrent:thread ==> 10
section name: db
items:
[('db_port', '3306'), ('db_user', 'root'), ('db_host', '127.0.0.1'), ('db_pass', 'password')]


db:db_port ==> 3306
db:db_user ==> root
db:db_host ==> 127.0.0.1
db:db_pass ==> password
