How do I identify what is on my python path (where python looks to import modules)?
View show_python_path.md

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?
View rounding_decimals.md

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.

Original Value

View runner.py
"""
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).
