Extend eval test of standard functions to cover python engine.

[domsmrz]

• closes #xxxx (Replace xxxx with the GitHub issue number) (no issue created)
• Tests added and passed if fixing a bug or adding a new feature (not applicable)
• All code checks passed.
• Added type annotations to new arguments/methods/functions. (not applicable)
• Added an entry in the latest doc/source/whatsnew/vX.X.X.rst file if fixing a bug or adding a new feature. (not applicable)

IIUC the standard functions are (now?) supported in both engines and we can have tests for that.

Thanks for the PR, is there an associated issue?

None that I'm aware of. I sort of randomly noticed this when I was trying to understand how does eval work. I was thinking about submitting an issue first but given that this is purely test change it doesn't feel like a bug nor a feature. Anyway, given the nature of the change and the very small size I figured that the easiest way forward would be just submit the PR.

Let me know if I should do anything else (or that we just don't want to merge this for any reason -- if that is the case).
