Answer 1

Make sure you have all the dependencies installed in your environment. You can use pip to install comtypes.client, simply pass this in your terminal:

pip install comtypes

You can download _ctypes from sourceforge: https://sourceforge.net/projects/ctypes/files/ctypes/1.0.2/ctypes-1.0.2.tar.gz/download?use_mirror=deac-fra

Using docx2pdf does seem easier for your task though. After you converted the files you can use PyPDF2 to append them.
