Get Python Tornado Version?

问题:

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'
