So I have one csv with 'films' in a database that have a unique ID
movie_title | ID | popularity spider-man unique ID 4.2 captain marvel unique ID 9.9
Then about every week, I would like to update that popularity with a new one from another list of movies.
New movie list:
movie_title | ID | popularity spider-man unique ID 5.5 captain marvel unique ID 7.4
How can I merge these two csv and output a new csv with only the value popularity updating? I have other values that also change over the week, but I just did popularity for simplicity. The unique ID must be in the new csv as well not only the changes; because, when I resubmit back to the database that is the only way that it will update with the ID.
The second list does not contain the ID's.
