Ref : https://www.python.org/dev/peps/pep-0632/#migration-advice

Something like below can be used with sysconfig that is compatible.

>>> import os, sysconfig
>>> os.path.dirname(sysconfig.get_config_h_filename())
'/usr/include/python3.8'
>>> import distutils
>>> distutils.sysconfig.get_python_inc()
'/usr/include/python3.8

@tirkarthi thanks, we are very much aware of the deprecation of distutils. We only seem to be using it directly in two places in setup.py, so it should not be hard to fix that up - let's do that before the next release.

I assume that you're just seeing a warning, and nothing actually broke?

Yes, it's only a deprecation warning during function calls. I am just raising issues in top pypi projects regarding distutils and pywt was one of them.
