What is your use case ?

There is no default branch set *before* the first push, so you should do:

   bzr push <target>

You don't have to specify it *after* the first push, you can just do:

   bzr push

You can override it at any time:

  bzr push --remember <target>

From a non-python script, bzr info is the way to go.
