With other packages I can do the following: print <modulename>.__version__ Source: How to check version of python modules? 回答1: 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) ).
