 Its main use has been in education, but it has also been used in commercial or research settings.VPython was first used in introductory physics courses at Carnegie Mellon and then spread to other universities and eventually high schools, especially in connection with the Matter & Interactions curriculum.A related development due to David Scherer and Bruce Sherwood is GlowScript, which makes it possible to write and run VPython programs in a browser, including on mobile devices, thanks to the RapydScript Python-to-JavaScript compiler, created by Alexander Tsepkov.
