Hi Jim,

and thanks for the response.

Did you succeed to import the Python bindings with  `import gnucash`?

Sure, as I mentioned:

Other gnucash related OS packages:

Package: python3-gnucash
Version: 1:4.8-1build2
State: installed
Section: universe/python
Maintainer: Ubuntu Developers <ubuntu-devel-discuss at lists.ubuntu.com>
Architecture: amd64
Depends: libc6 (>= 2.14), libglib2.0-0 (>= 2.12.0), libpython3.10 (>=
3.10.0), python3 (< 3.11), python3 (>= 3.10~), python3:any

As you can see from Depends, it installs bindings for python3 >= 3.10~ <
3.11.
3.10.12 is the version of Python3 installed on my OS, so this should
conform (no wonder, since it is an OS package). Maybe some other libraries
(like libc6?, etc.) are incompatible between gnucash and python3-gnucash?

Can you do `import gnucash` from a Python REPL?

Thanks,
    Zsolt
