C++ namespace imported as a "class" instead of "module"

ROOT
3

Dear Wim,

Thank you for your reply!
From the separate post, that’s what I hoped to be a solution.
Here’s a post I found: ‘using namespace’ equivalent

But this does not seem to work. In particular, I tried and get the following error:

>>> import ROOT
>>> ROOT.mytry
<class 'ROOT.mytry'>
>>> from ROOT.mytry import Trial
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named mytry

What am I missing?
Thank you for your time and I’m sorry for questioning further.
