How I can parse to float the string data of a specific column in a dataframe?

Question

df = pd.DataFrame(data=dict_kv, columns = header)
df.head()
Provinces Confirmed cases Confirmed deaths Probable deaths
0 Azuay 10658 195 12
1 Bolívar 2111 66 12
2 Cañar 2110 83 7
3 Carchi 3053 104 1
For instance, for this dataframe I only want parse to float the data in the columns:
Confirmed cases, Confirmed deaths, Probable deaths

Answer 1

You can create a new dataframe with the columns you want... something like this
new_df=df['Confirmed cases', 'Confirmed deaths', 'Probable deaths']
