pandas: to_numeric for multiple columns

Question

I\'m working with the following df:

c.sort_values(\'2005\', ascending=False).head(3)
      GeoName ComponentName     IndustryId IndustryClassification Descri         


        

Answer 1

another way is using apply, one liner:

cols = ['col1', 'col2', 'col3']
data[cols] = data[cols].apply(pd.to_numeric, errors='coerce', axis=1)
