What is on my python path?

Knowning where python is trying to find files is important.

Let's say try to import a module and you get an Import Error.

Like this:

>>>  import foo

How do I round to 2 decimals?

In python, you have floats and decimals that can be rounded. If you care about the accuracy of rounding, use decimal type. If you use floats, you will have issues with accuracy.

All the examples use demical types, except for the original value, which is automatically casted as a float.

To set the context of what we are working with, let's start with an original value.

	An alternative Django ``TEST_RUNNER`` which uses unittest2 test discovery from
	a base path specified in settings, rather than requiring all tests to be in
	``tests`` module of an app.

	If you just run ``./manage.py test``, it'll discover and run all tests
	underneath the ``TEST_DISCOVERY_ROOT`` setting (a path). If you run
	``./manage.py test full.dotted.path.to.test_module``, it'll run the tests in
	that module (you can also pass multiple modules).

	Returns a list of country counts in a folder of Marc xml records &
	coorsponding records that exist in the current database. This is used to help
	understand how close the Marc xml records are to the existing ChronAm dataset.

	To run this file: python extract_cntry_from_worldcatrecs.py $path_to_bib_folder
