IMO Go's standard library (http://golang.org/pkg/) is at least as complete as Python's for everyday programming and includes some things that Python's standard library doesn't such as crypto, image processing and a production ready HTTP server.
Right now I'd say Python has an advantage in comprehensive frameworks such as Django or Numpy but I think it's just a matter of time before similar frameworks emerge for Go.
