For that scenario (if you can’t use the Linux container on Chrome OS, which works even without flipping the devmode switch), repl.it is fantastic. It builds a fully working python (or C, or Java, or even a polyglot one that’s just Linux) environment, automatically deals with dependencies (if you type import pandas and it’s not installed, it gets installed), has synchronous collaboration and can even auto grade work with unit tests (at least, it was in beta last I checked). It’s the holy grail of learn- to-code software and it kicked butt in the class I used it in.
