As Richardson Porto pointed out, /sdk is the SOAP endpoint. There is also web-ui oriented interface called the mob at /mob.
Overall the API documentation is generic to any of the SDK kits (Python, Perl, dotNet, Java, etc).
For Python, you'll probably want to use pyvmomi: https://github.com/vmware/pyvmomi
You'll have to know the utility functions for each SDK (they vary) and there are some quirks between how you instantiate the API objects.
