Right now you can only get .py domains as subdomains of these second-level domains:

  - com.py
  - coop.py
  - edu.py
  - mil.py
  - gov.py
  - org.py
  - net.py
  - una.py

And there are some domains used like nic.py. Possibly Chrome could fall back to search if its not one of the subdomains.

But this is clearly a case where the idea of search box and url bar in one field does not work. This will happen more often as we get more of those random TLDs.
