Reinteract is described as 'System for interactive experimentation with Python. Reinteract worksheets contain Python code combined with the results of that code, formatted as text or graphical plots. Youu can go back and edit previously entered statements, and the results will update' and is an app in the development category. There are more than 25 alternatives to Reinteract for a variety of platforms, including Windows, Linux, Mac, Python and BSD apps. The best Reinteract alternative is R (programming language), which is both free and Open Source. Other great apps like Reinteract are GNU Octave, MATLAB, SageMath and Mathematica.
