Get the Python Tornado version

Question

How do I get the current version of my Python Tornado module version?

With other packages I can do the following:

print <modulename>.__version__

Have you tried using dir to see if there are any attributes that might be it? — jonrsharpe

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.

Is this specific to python tornado -> or should we be trying these properties on other packages which don't have .__version__ ??

There's no standard about this, so it's worth a try on other packages. version and version_info are the names used in the sys module, and I know that pycurl uses the same names (although in pycurl version_info is a function instead of an attribute)

If using Ubuntu, open a terminal and type python. Then import tornado and the write command tornado.version.

You will get output like '4.2.1'.

With no reference, or reason I tried the following:

print tornado.version

which seems to do the trick.
