Rename “None” value in Pandas

Question

This is probably super simple but I just can not find the answer. I import data using GeoPandas from a shape file. Turn that into pandas DataFrame. I have a object

Answer 1

The simplest thing to do is just:

sala['N10'].replace('None', 'vcv', inplace=True)

that should work.

If they were true NaN values then calling fillna would've worked.

e.g.

sala['N10'].fillna(value='vcv', inplace = True)

also what I suggested in my comment:

sala.loc[sala['N10'].isnull(), 'N10'] = 'vcv'
