How do I get the current version of my python Tornado Module Version?
With other packages I can do the following:
print <modulename>.__version__

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)). The fourth value of version_info will be negative for betas and other pre-releases.
回答2:
With no reference, or reason I tried the following:
print tornado.version
which seems to do the trick.
回答3:
If using Ubuntu open terminal type python , then import tornado, the write command tornado.version
and u will get output like '4.2.1'
