Question about printing from my classes?

[brombo]

Is the following correct?  As long as the classes I write have _sympystr and _latex members the printing using sympy and my objects is transparent.

One more question.  I am running Ubuntu 22.04 and have not been able to set a PYTHONPATH to include the directories with my code in them.  Has something changed in Ubuntu 22.04.  What do you do to put the sympy code in the path?

That should be enough. Make sure you follow the guidelines at
https://docs.sympy.org/latest/modules/printing.html#common-mistakes
for recursively printing subexpressions. If you care about the Unicode
pretty printer, you will need to a printer for it as well.

As far as I know, PYTHONPATH should work the same no matter what
platform you use. You can check sys.path in Python to see what paths
it uses to import things.
