Find python lxml version

Question

How can I find the installed python-lxml version in a Linux system?

>>> import lxml
>>> lxml.__version__
Traceback (most recent call last):
  F

I assume you want to determine lxml's version programatically from Python. Since lxml does not provide this information via way of a typilca __version__ attribute on the top-level package you will have to resort to using setuptools' pkg_resources.require() function:

>>> from pkg_resources import require
>>> match = require("lxml")
>>> match
[lxml 3.3.0beta1 (/home/prologic/lib/python2.7/site-packages)]
>>> lxml = match[0]
>>> lxml.version
'3.3.0beta1'
