# # 2、sys.exit(n) 退出程序，正常退出时exit(0)
# # # 退出程序，正常退出时exit(0)
# ------------------------------------------------------------

# # 3、sys.version
# # # 获取Python解释程序的版本信息
# # # ==>>>应用场景：当程序拷贝到其他的电脑的时候，需要进行对电脑的运行环境进行获取，
# # # 以保证程序在其他的操作系统环境下能够正常的运行
# ------------------------------------------------------------
# ------------------------------------------------------------
# # 4、sys.maxint
# # # 最大的Int值 (python 2 中才有这个模块)
# ------------------------------------------------------------
# ------------------------------------------------------------
# # 5、sys.path
# # # 返回模块的搜索路径，初始化时使用PYTHONPATH环境变量的值
# ------------------------------------------------------------
# ------------------------------------------------------------
# # 6、sys.platform
# # # 返回操作系统平台名称
