方式1：argparse
argparse，是Python标准库中推荐使用的编写命令行程序的工具。也可以用于读取配置文件。
字典样式的配置文件*.conf
配置文件test1.conf
{ "game0": { "ip":"127.0.0.1", "port":27182, "type":1 }, "game1": { "ip":"127.0.0.1", "port":27183, "type":0 }, "game2": { "ip":"127.0.0.1", "port":27184, "type":0 }}
config.py

运行
启动脚本：python test.py test.conf --game=game0

方式2：ConfigParser
ConfigParser是Python读取conf配置文件标准的库。
中括号下设置子项的配置文件*.conf、或者*.ini
test2.conf
[game0]ip = 127.0.0.1port = 27182type = 1[game1]ip = 127.0.0.1port = 27183type = 0[game2]ip = 127.0.0.1port = 27184type = 0
test2.py

动态添加配置：
# add cf.add_section('test3') cf.set('test3','id','123') cf.write(open(filename,'w'))
详见：
方式3：用变量（常量）作为配置文件格式。*.py
配置文件：config.py
LISTEN_PORT = 4444USE_EPOLL = True
导入配置：myread.py
import configport_num = config.LISTEN_PORTif config.USE_EPOLL: print(config.USE_EPOLL)
