It is a library which will serve as a base to develop circuit based applications and educational software on top of it. BinPy is a clear representation of fundamentals. Everything has been written from scratch such as gates, logical operations, etc. This package does not depend on any external library other than pure Python. It aims to extend the hardware programming concepts to Python.
Here's an example of SR latch constructed from a pair of cross-coupled NOR gates
from BinPy import *
NOR1 = Nor('NOR1') #First NOR gate
NOR2 = Nor('NOR2') #Second NOR gate
NOR2.C.connect(NOR1.B) #Connecting output of second NOR with input of first NOR
NOR1.C.connect(NOR2.A) #Connecting output of first NOR with input of second NOR
NOR1.A.set(1);NOR2.B.set(0) #Set state
print 'Q: ',NOR2.C.getState(), '\t','Q\': ',NOR1.C.getState()
NOR1.A.set(0);NOR2.B.set(1) #Reset state
print 'Q: ',NOR2.C.getState(), '\t','Q\': ',NOR1.C.getState()
NOR1.A.set(0);NOR2.B.set(0) #Hold state
print 'Q: ',NOR2.C.getState(), '\t','Q\': ',NOR1.C.getState()
NOR1.A.set(1);NOR2.B.set(1) #Invalid state
print 'Q: ',NOR2.C.getState(), '\t','Q\': ',NOR1.C.getState()
Output
Q: True Q': False
Q: False Q': True
Q: False Q': True
Q: False Q': False #Invalid StateOperations, Combinatonal Logic and Algorithms

Minimized Boolean Equation : ((NOT B) OR (NOT A))BinPy also comes with a console that is a simple wrapper around the classic python console from which you can directly use the BinPy Resources.
To start it, simply issue:
$ binpy
if BinPy is installed in your path.
