Python Forum

Hello,
I am totally new to python and not sure this is the correct place to ask a question.
I want to remove receipts which have opposite values (Y vs N,1 vs -1 etc.).if each receipt's row has opposite row. I.e. if also will be row 500.2 (with any content) - receipt 500 will not be removed.
Does any suggest me the best way to do with python script? I am a power bi developer and power bi accept python script.
Please see below link for data set and expected result.
