The main difference is that the R function is vectorized. If states = [TX, CA, NY] and numbers = [1, 2, 3] then the paste function should return ['TX1', 'CA2', 'NY3']. R's problem is simpler because python has more types to worry about: lists, numpy arrays, pandas Series, so it is not clear what the return type should be if numbers is a numpy array and states is …
