Quantum Toolbox (quanguru.QuantumToolbox)

QuantumToolbox consists purely of Python functions (no other objects) that create and/or use matrices. Bold parts of the previous sentence highlight two main ideas of QuantumToolbox.

It only contains Python functions to make it familiar with a broader audience, so that anyone without any interest in object-oriented programming can still contribute to QuantumToolbox, and the second idea is to use scipy sparse (csc matrix) as default. Matrix creations should be sparse as default and return .A (or .toarray()) of the created sparse if sparse=False. Any function manipulating matrices should be designed to be independent of sparse or array, if possible.
