Yes ; in Debian: - sagemath's standard elliptic_curves is sagemath-database-elliptic-curves (I'm the maintainer) ; - sagemath's optional database_cremona_ellcurve will be sagemath-database-cremona-elliptic-curves (I'll be the maintainer). > I have tried your new py code to produce a new version of the database > file: it appears to work perfectly, and will compare it with what the > existing Sage code creates.

I'm all for using a simple standalone Python script instead of depending on all of sagemath...
