pyParallel is a library for accessing a computer's parallel port (LPT, IEEE 1284) from Python. It is a sister project of pySerial, for serial communication, made by the same developer, and was used in experiments that control simple hardware such as LEDs or relays by directly reading and writing the data, control, and status pins. It supports Linux and Windows, but on modern PCs, which no longer have parallel ports, its usefulness is limited and it is barely maintained.
