Find which version of package is installed with pip

Question

Using pip, is it possible to figure out which version of a package is currently installed?

Answer 1

import pkg_resources
packages = [dist.project_name for dist in pkg_resources.working_set]

   for count, item in enumerate(packages):
      print(item, pkg_resources.get_distribution(item).version)
except:
    pass here

The indentations might not be perfect. The reason I am using a Try- Except block is that few library names will throw errors because of parsing the library names to process the versions. even though packages variable will contain all the libraries install in your environment.
