I'm reviewing a PR for Apache Beam that includes code based on code from another project.
The other project uses the Python License (https://github.com/python/cpython/blob/170ea8ccd4235d28538ab713041502d07ad1cacd/LICENSE).
My questions are:
1. Is it okay to accept this code?
2. If so, how do we properly attribute the license?
I was thinking of placing it in a separate file with an appropriate license header.
3. Does the top level NOTICE file need to be updated as well?
