How do I debug a python script in the script snap

@Sahil I am not sure how you design your pipeline, but just for quick fix the deletion issue, you can choose the below option in your File delete snap. One more thing, Unique will only remove those duplicate record if all set of attribute are same. So better if you have only concerns about filename, then add one mapper before unique and only map exact file name to delete. Then it should discard duplicate filename.
