problem of having different projects requiring different versions of Python.

For example, it becomes very easy to install Python 2.7 for compatibility in

one project,whilst still using Python 3.4 as the default interpreter.

Unlike block comments, docstrings are built into the Python language itself.

This means you can use all of Python's powerful introspection capabilities to

access docstrings at runtime, compared with comments which areoptimised out.

Docstrings are accessible from both the `__doc__` dunder attribute for almost
