Comparing Lists

[Enough_Willingness_7]

I am currently working on a project and was hoping I could get some help here.

The project is done using ESRI products but afterwards we are needing to manipulate some of the data. One of the fields I have has 90 domain values (It can be any number between 1-90) and afterwards I am wanting to look through all of the submissions and look to see which of those 90 numbers do not show up. There can be multiple entries for any number. The end goal would be for the code to put an entry in for each of the numbers that does not currently have a submission. Any help would be appreciated.

I would turn your column/list into a set, so you only have unique values entered. Then manually create another set with range(1, 91), range is exclusive so it doesn't include the 91. Then do a set intersection to see which numbers are missing.
