compound columns using IN - rregorr - Jul-19-2019 I have a dataframe with 4 columns identifieds with names single and compounded "Identificação Única", "Nome", "Código da Rubrica" and "Valor" and I would like to get some values from these columns. e.i. numbers 10 and 11 from "Identificação Única" or numbers 1 and 2 from "Origem". The code following just works if the name of the columns is single, but it doesn't works if it is compound. For example: #f0619.query('Origem in ["1", "2"]') # it works fine f0619.query('Código Rubrica in ["27","69"]') # it doesn't works, but if I rename these column to, let's say, Codigo_Rubrica, it works fine.How can I to work with compound columns using "IN"? RE: compound columns using IN - scidam - Jul-20-2019 Are you allowed to use something else instead of .query . You can try, e.g. df.iloc[:, 27].str.contains("Rubrica") & df.iloc[:, 69].str.contains("Rubrica")Or may be I misunderstood something... RE: compound columns using IN - rregorr - Jul-22-2019 I think that you didn't understand. I can not to use "loc". I prefer to use query this way: f0619.query('CódigoRubrica in ["27","69"]') #this way, it works.But, when the column has two names, two string separated by spaces, I got error. For example: f0619.query('Código Rubrica in ["27","69"]')And I don't want rename the columns, and I don't want remove the empty spaces of words, because it is confuse. I have to use the column the way it is. RE: compound columns using IN - scidam - Jul-22-2019 It seems that functionality is supported by the latest version of Pandas only. Unfortunately, I don't have Pandas 0.25+ installed on my computer, so try the following suggestion. |
