argvdict = {}
for i in sys.argv[1:]:
    argvdict[tuple(i.split("="))[0]] = tuple(i.split("="))[1]

config.read(argvdict["--config-file"], encoding='utf-8')
CONF = _Config_(config)

#配置文件格式test.conf
[DEFAULT]
class = midlle

[USER]
name= lisi

调用方法

##main.py
from config import CONF

print("class is:", CONF.class)
print("user name is:". CONF.USER.name)

运行方法：
python main.py --config-file=test.conf
