Nominatim usage policy: HTTP Referers and User-Agents

Hi all,

I've got a question on the Nominatim Usage Policy that will probably sound stupid to many of you, but have very limited experience with APIs and just want to make sure to get it right. The policy states:

Provide a valid HTTP Referer or User-Agent identifying the application (stock User-Agents as set by http libraries will not do).

and I simply don't know what this means - if I were to write a Python script using the requests library in combination with the API and do a simple requests.get(url), would that be OK (given I'll abide by the other rules, like the request limit), or would that exactly be what falls under "stock User-Agents as set by http libraries"? In the latter case, what would I have to change to make it comply?

Thanks for the help!
