Add functinality to reference "False" item.

example: bool_series = df.duplicated(keep='first', reference=yes)

  1. Dog
  2. Cat
  3. Dog

output 1. False,NaN 2. False,NaN 3. True, 1

This would allow you to flag the "is duplicated items" (True), skip processing, but then at a later time, reference the output of the False items.

I need to keep the data integrity, but stop duplicate processing if it's a duplicate.

Hi @djjeremiahj

It's not clear what you're asking - could you open a new issue and fill in the template please?
