constitution doesn't work on python3

[sunglyoungKim]

Hello,
I am using Ubuntu 22.04 with Python 3.0

I have installed openbabel 3.1.1 and rdkit 2022.9.3 (installed by pip).

When I run constitution for mol I got TypeError. I believe round behavior has been changed from python2 to python3. Could you fix it this error?

python3 constitution.py

CCCC
[21:19:38] WARNING: the onlyHeavy argument to mol.GetNumAtoms() has been deprecated. Please use the onlyExplicit argument instead or mol.GetNumHeavyAtoms() if you want the heavy atom count.
