I am trying to compare the occurrences of codes from a column within feature classes against a list from a spreadsheet column and then add these to a dictionary where the feature class name is the key and the values are a count of unique occurrences between the two columns. I then need to sum all the value counts for each key. The keys of this dictionary will be String variables. The values of this dictionary will each be a list of numbers. Your function should create a new dictionary. The keys of the new dictionary should be the same as the keys of the original dictionary. The values of the new dictionary should be the sum of the respective values in the the
