Looking for some simple code to run either in Field Calculator (preferred) or in a python script on a table to create a field and add incremental numbers to that field based on repeating values of another field, for all records.  I've already permanently sorted the table, which I need to do before incrementing the duplicate records.  I can create the field no problem to minimize steps necessary, if someone can provide the basic code for the increment based on a field.  Thanks.

Example table:
FieldA     Dups (created)
3            1
3            2
3            3
1            1
1            2
1            3
1            4
8            1
8            2
