Can I use a PyPI package in closed-source software?

Last updated

TL;DR: A BSD-3-Clause package, shipped closed-source: Yes. An LGPL-3.0 package, distributed: Yes. A GPL-3.0 package, modified and distributed: Yes. It depends on the package's declared license; MIT, BSD and Apache-2.0 are common on PyPI. Pass the project URL as source_url and a2ally reads it.
