We can assume this is a fragment of a function, since it ends with a return.

You don't say what this function is supposed to return, and you don't 
supply the source for dumps().

So, applying my crystal ball and figuring you want a list, just write 
dumps so it puts the create-new-address entry at the end.  You could 
ensure that by changing the name create-new-address to 
zzz-create-new-address, and simply doing a sort.  Or you could simply return
    return dumps(addresses) + "Create new address"

and not put it into the dictionary at all.
