ModuleNotFoundError vs. ImportError

[CBroz1]

We typically run a try/except on optional dependencies, excepting an ImportError. Depending on the user environment, this may raise ModuleNotFoundError. This was the case in VSCode's Jupyter debugger view.

An easy enough solve would be to...

try:
    import x
except (ModuleNotFoundError, ImportError) as e:
    x = None # We're inconsistent on this, and it helps for static linters
    logger.warning(e)

Which cases cause the ModuleNotFoundError?

[CBroz1]

I saw this declaring some custom table in VSCode-managed Jupyter yesterday - specifically, dj_mixin.py raised ModuleNotFoundError attempting to import Pynapple

I am confused as to why it perceives this as a module rather than as a package.
