Example:
In [3]: df = pd.DataFrame([['GD', 'GX', 'FJ'], ['SD', 'SX', 'BJ'], ['HN', 'HB' ...: , 'AH'], ['HEN', 'HEN', 'HLJ'], ['SH', 'TJ', 'CQ']], columns=['p1', 'p2 ...: ', 'p3'])In [4]: dfOut[4]: p1 p2 p30 GD GX FJ1 SD SX BJ2 HN HB AH3 HEN HEN HLJ4 SH TJ CQ
If you only want two rows whose p1 is GD and HN, you can do this:
