Examples for Python 2 or 3

Obtaining a token with the flask and requests libraries

JSON with the Requests library
SOAP with the Suds library
XML with the Requests and PyXB libraries

Installing additional libraries

You can use the pip utility for installing libraries (Flask, Requests, Suds, PyXB, and others):
pip install %package_name%

The pip utility is included in Python 2 beginning with version 2.7.9, and in Python 3 beginning with version 3.4. If you are using an earlier version of Python, you need to install pip. For example, you can use the script https://bootstrap.pypa.io/get-pip.py.
