Anything and everything. In addition to Django and ML (which you mention), there's a lot of systems programming that can be done with Python. I recently left a position where I automated systems tools using Saltstack and Python, Gitlab CI/CD and Python to automate a lot of data loading and wrote some services using Flask and DRF. The CI/CD project had me make a satellite system of Docker images to interact with SMB and REST interfaces. That was a lot of fun, akin to making basic Unix tools for a multi-OS hoard (think cp mv and rm except the endpoints are services instead of files). Made me realize that in the Docker world we have to adjust our expectations for what you pass between commands. It's no longer text on a pipeline, it's filesystems passed between containers.
