Ask HN: Who is using Python in the browser or mobile platforms?

For nearly a decade now, we've been talking about Python running in places other than the CLI of a server.

There have been a bunch of efforts to build a toolchain allowing Python to run "anywhere" - Beeware / Briefcase, Kivi, etc.

When connectNative started to be a topic of wide conversation, there was a wave of optimism that this was going to be the way that Python ran in the browser. But is anybody doing it?

In 2020, if you want to target CLI, browser, and mobile, all with one codebase, do you still need to use javascript?
