Thank you for providing an actual code example (though not one I can
run, since it isn't a complete Python program).

Particularly, thank you for providing the *actual* error output; this
makes it much clearer what is happening.

It's always best to show the complete error output since usually there
are details in the output that narrow down the problem.

This is indeed a problem specific to the types defined by Sage. You'll
need to start a discussion in a Sage-specific discussion forum.

You will likely still need assistance with Python to continue with this.
Once you have a better idea what part is Sage-specific and what part is
general Python, feel free to ask here.

Or if you prefer, there is a beginner-level Python discussion forum at
