How to remove rows in a Pandas Dataframe with a specific column containing numbers only?












3















Lets say I have this DF:



ID     IGName          Date_created
0 BananaMan 09/10/2018
1 Superman247 10/10/2009
2 123456789 08/03/2011
3 Nameless101 07/12/2012


I want to be able to remove all the rows in the DF where the IGName is only numbers.



Like how in this example, row 3 is all numbers. I want to be able to keep the names alphanumeric rows but not the rows with ONLY numerics.



I want the result to look like this:



ID     IGName          Date_created
0 BananaMan 09/10/2018
1 Superman247 10/10/2009
3 Nameless101 07/12/2012

          You could do:



          import pandas as pd


          data = [[0, 'BananaMan', '09/10/2018'],
          [1, 'Superman247', '10/10/2009'],
          [2, '123456789', '08/03/2011'],
          [3, 'Nameless101', '07/12/2012']]

          df = pd.DataFrame(data=data, columns=['ID', 'IGName', 'Date_created'])

          df = df[~df['IGName'].str.isnumeric()]

          print(df)


          Output



             ID       IGName Date_created
          0 0 BananaMan 09/10/2018
          1 1 Superman247 10/10/2009
          3 3 Nameless101 07/12/2012


          From the documentation:




          Check whether all characters in each string in the Series/Index are
          numeric. Equivalent to str.isnumeric().




          Note that this solution assumes the column 'IGName' is of type string, otherwise you need to cast it to string, doing something like (as mentioned by @RafaelC):



          df['IGName'] = df['IGName'].astype(str)

          • I mean if you have mixed types in the same column. For example, if in your data, you had [2, 123456789, '08/03/2011'] instead of [2, '123456789', '08/03/2011']

          Use df[...]:



          print(df[~df['IGName'].str.isnumeric()])


          Or:



          print(df[df['IGName'].str.contains(r'D+')])


          Both Output:



             ID       IGName Date_created
          0 0 BananaMan 09/10/2018
          1 1 Superman247 10/10/2009
          3 3 Nameless101 07/12/2012


          If IGName has integers do:



          print(df[pd.to_numeric(df.IGName, errors='coerce').notnull()])

          @RafaelC do you mean if the column is of type int or float?

          I mean if you have mixed types in the same column. For example, if in your data, you had [2, 123456789, '08/03/2011'] instead of [2, '123456789', '08/03/2011']

          Does it suffices to cast the column to string first?

          As a matter of fact, yes ;}. Use .astype(str)

          Use df[...]:



          print(df[~df['IGName'].str.isnumeric()])


          Or:



          print(df[df['IGName'].str.contains(r'D+')])


          Both Output:



             ID       IGName Date_created
          0 0 BananaMan 09/10/2018
          1 1 Superman247 10/10/2009
          3 3 Nameless101 07/12/2012


          If IGName has integers do:



          print(df[pd.to_numeric(df.IGName, errors='coerce').notnull()])
