AFAIK, there is not a separate set of IBM documentation for the python language as you normally expect for an IBM language product (i.e., no "Language Reference" or "Programmer's Guide" manuals). You can however use the normal web-based python language documentation you would use for any other platform. Also AFAIK, the z/OS python implementation includes the entire python standard library.
As for examples, try signing up for the IBM Zxplore student website (https://ibmzxplore.influitive.com). After you complete a sufficient number of the fundamental and advanced challenges, there are at least one or two challenges that require you to use python to complete the challenge on their z/OS system. Once you get to complete the USS1 challenge and are allowed to login to the Zxplore z/OS Unix environment, you will have access to the python3 installed on their LPAR and you can experiment with it yourself (carefully! The disk space for students there is quite small, so no production volume data uploads please!). However, there are no python virtual environments allowed on Zxplore's z/OS system (package virtualenv/venv is not installed), so you can't install any python packages besides what the administrators provide in the global site-library. I will say that having the default shell of bash on the Zxplore z/OS Unix system is extremely helpful for exploring python there. If you don't have bash installed on your z/OS system, I highly recommend it. I personally have not yet tried to use python from JCL, only from the z/OS Unix shell. You can invoke it from JCL using BPXBATCH or suitable substitute though.
