Debug dll file used in python script IDA

I am fairly new to RE on windows.
I have a python script which via ctypes uses functions from a dll.

I don’t know if it’s possible, but I would like to debug the dll used in the python script (the dll is not executable).

I tried to attach to the python process, but it exits right after, and I also tried to start the process from IDA, but I get a python console and my breackpoint is never reached.

So how can I do it?
