Using the Python API to connect to Azure Blockchain Workbench

Hey guys,

I'd really appreciate some advice connecting to the app as a user. I have created the little "Hello, Blockchain!" example but the API guide, https://github.com/Azure-Samples/blockchain/blob/master/blockchain-workbench/rest-api-samples/python/README.md, seems to be missing necessary bits of code. Fortunately I was able to piece it together such that I can now send requests to the app, but I cannot figure out how to do so as a particular user, so trying to get a list of all applications returns "None", and current user returns as "None".

I would really appreciate it if there's a fully-fleshed, working example somewhere that I can learn from.

Thanks for reading.
