SPYSE - A Semantic Search Engine for Python Packages and Modules

Code reuse is a common practice among software developers,whether novices or experts. Developers often rely on online resources in order to find code to reuse. For Python, the Python Package Index (PyPI) contains all packages developed for the community and is the largest catalog of reusable, opensource packages developers can consult. While a valuableresource, the state of the art PyPI search has very limitedcapabilities, making it hard for developers to find useful, highquality Python code to use for their task at hand.We introduce SPYSE (Semantic PYthon Search Engine), a Web-based search engine that overcomes the limitations of the state of the art, making it easier for developers to find useful code. The power of SPYSE lays in the combination of three different aspects meant to provide developers with relevant,and at the same time high quality code: code semantics,popularity, and code quality. SPYSE also allows searching for modules, in addition to packages, which opens new reuseopportunities for developers, currently not supported.
