The PLIB3.CLASSES Package

The following classes are available in the plib.classes namespace:

• The StateMachine class implements a basic finite state machine with customizable code to be run at each state transition.

Installation

The simplest way to install PLIB3.CLASSES is by using pip:

$ python3 -m pip install plib3.classes

This will download the latest release from PyPI and install it on your system. If you already have a downloaded source tarball or wheel, you can have pip install it directly by giving its filename in place of “plib3.classes” in the above command line.

The Zen of PLIB3

There is no single unifying purpose or theme to PLIB3, but like Python itself, it does have a ‘Zen’ of sorts:

• Express everything possible in terms of built-in Python data structures.

• Once you’ve expressed it that way, what the code is going to do with it should be obvious.

• Avoid boilerplate code, and boilerplate data. Every piece of data your program needs should have one and only one source.
