Wow, the function naming alone is terrible.

    for i in range(len(path_parts) - 1, -1, -1):
        if not path_parts[i] in resource_types and path_parts[i] in resource_tokens:
            return resource_tokens[path_parts[i]]

This bit of iteration is painful to look at as well.

Some optimisations to get it to web-scale on TempleOS were obviously necessary.

The Client APIs are kind of free: https://github.com/Azure/azure-sdk-for-python/blob/master/LI...

I didn't compare the code, but maybe it's autogenerated from a more C-like language, making a bit awkward syntax for a language like Python?
