Useful Things I learnt

1. inplace = True/False in df.drop

• df.drop([column_name], axis=1, inplace=False) -> default

  • returns the df hence, should be df = df.drop([column_name], axis=1, inplace=False)

  Else, if inplace=True, it is renamed in its place df.drop([column_name], axis=1, inplace=False) should update the df!
