Geocoding the addresses

Now we know how to read and write data, let's now loop over the addresses from the file and store the results into another .csv file. For that, we'll create another function that loops over the addresses and geocodes them one by one. One reason to do so is to make the code more robust; currently, if something goes wrong with a specific request (say, the address is not found), our geocode function will raise an error, halting the whole process and, potentially, leading to the loss of all previously geocoded data. Arguably, a better way would be to keep the script running and store the dataset, reporting issues and the corresponding rows of the original dataset separately. So, let's catch errors and append them and the ...
