   sage is using now python3, since january 2020 and version 9.0. So this file is no longer working.

   Thanks, looks good!

   I noticed that secp256k1.sage does not work either with the current sage. This should also be easy to fix. Feel free to add a commit or indicate here that you’re not willing to do this (then we can do it in another PR).

   Conversion to python3 is not an easy task. It usually requires care from somebody knowing the code.
