推荐答案

Tornado同时具有tornado.version和tornado.version_info，这是一个供人们食用的字符串(当前为"4.2")，而tornado.version_info是一个数字元组，更好地用于程序比较(当前为(4, 2, 0, 0)).对于Beta和其他预发行版，version_info的第四个值将为负.

Tornado has both tornado.version, which is a string for human consumption (currently "4.2"), and tornado.version_info, which is a numeric tuple that is better for programmatic comparisons (currently (4, 2, 0, 0)). The fourth value of version_info will be negative for betas and other pre-releases.
