Apple photos find duplicates9/20/2023 Your best bet is to sort the list first using itemgetter() to select the fields to be matched as key. I think this may be getting beyond the Learning Python book. The first, fourth and fifth lists would be duplicates and therefore all lists should be updated as follows: However, in this case a "duplicate" list is one that has equal values in several preselected fields, but not all fields (there are no "true" duplicates).įor example: if this were the original data from a 5 item list of lists and duplicate is defined as having equal values in the first and third fields: I am looking to "tag" duplicates by adding an extra field to the end of an individual list. Each list contains multiple items of varying types (maybe 10 items per list) The overall order of the lists is not relevant, but the order of the items in any individual list is important. I have (what I think is) a working solution but it has complicated flow controls and just isn't "pretty". I am looking for a Pythonic way to solve the following problem.
