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.
