SymPy Gamma
SymPy Gamma is a simple web application based on Google App Engine that executes and displays the results of SymPy expressions as well as additional related computations, in a fashion similar to that of Wolfram Alpha. For instance, entering an integer will display prime factors, digits in the base-10 expansion, and a factorization diagram. Entering a function will give its docstring; in general, entering an arbitrary expression will provide the derivative, integral, series expansion, plot, and roots.
