Python script for listing similar records.

[CariRuffino]

I need to automate a process with Python. I have a feature class with about 8000 records. About 1000 of those records are multiples that occured after changing over CAD data. These records represent parcels that could be an error from the CAD data or could be multi-part parcels, so a list of just the multiples would speed the process up.

If I understand your question, you could simply use the Frequency Tool.  The results will give you a field telling you how many times a particular record occurs.
