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.

• Python 2 vs Python 3
• python interpretor vs ipython vs code editor vs notebook
• Anaconda vs virtualenv vs no virtualenv (Advanced intro)
  • Anaconda cheatsheet

"""
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).
