My working directory d:\Works\Python\ has a package 'fitz' looks like this:

.....fitz\
.........__init__.py
.........fitz.py
.........utils.py
........._fitz.pyd

There is a statement in fitz.py:
.....return importlib.import_module('fitz._fitz')

It works fine under Python 3.4 interpreter:
>>> import fitz
>>>

But under Python 3.8 I get an exception:
>>> import fitz
Traceback(...
....
....
ImportError: DLL load failed while importing _fitz
>>>

I work under Windows7 64bit with Python 32bit. Can anyone help?

The Python C-API is Python version dependent.
Your `_fitz.pyd` may need to be recreated for Python 3.8.

It seems that I have to install pymupdf to use fitz. Thank you.
