Hi,
with pandas I obtain results!
Now I would calculate ratio beetween columns of my csv
import pandas as pd
pd.set_option('display.max_rows', 500)
df = pd.read_csv ('data_quartiere_2018.csv', usecols=
['Anno','Totale','Quartiere','Nati','80 e più soli','80 e
più','Minori','Scuola_infanzia (numero)'])
test = df.loc[df['Totale'] >= 31990,
print (test)
in particular I would calculate ratio beetween ('Nati'*100)/'Totale' when
['Totale'] >= 31990
How could fix it
