py-notify An unorthodox implementation of Observer programming pattern. Py-notify is a Python package providing tools for implementing `Observer programming pattern`_. These tools include signals, conditions and variables. Signals are lists of handlers that are called when signal is emitted. Conditions are basically boolean variables coupled with a signal that is emitted when condition state changes. They can be combined using standard logical operators (*not*, *and*, etc.) into compound conditions. Variables, unlike conditions, can hold any Python object, not just booleans, but they cannot be combined.
