python中获取打包成执行文件(exe)和脚本运行文件的路径

　代码：

import os
import sys

config_name = 'myapp.cfg'

# determine if application is a script file or frozen exe
if getattr(sys, 'frozen', False):
application_path = os.path.dirname(sys.executable)
elif __file__:
application_path = os.path.dirname(__file__)

config_path = os.path.join(application_path, config_name)
