The '''Armstrong Siddeley Python''' wasis an early [[United Kingdom|British]] [[turboprop]] engine that was designed and built by the [[Armstrong Siddeley]] company in the mid-1940s. Its main use was in the [[Westland Wyvern]], a [[Aircraft carrier|carrier-based]]-based heavy fighter. The prototypes had used the [[Rolls-Royce Eagle (1944)|Rolls-Royce Eagle]] piston engine, but Pythons were used in production aircraft. In this application, the Python was rated at 4,110 [[equivalent shaft horsepower]] (eshp).
