Py-Vollib

Deprecated transition package for vollib, a Python library for pricing and calculating option implied volatility using Black-Scholes, Black (1976), and Garman-Kohlhagen models. Version 1.0.7 is the final release; users should install 'vollib' (the canonical package) instead. py_vollib is published as a stub that depends on vollib and provides deprecated compatibility imports. Release cadence is low; actively maintained on GitHub under the vollib organization.
