Filling list nan values

Question

How to fill nan values with 0's in a list. I can do it for dataframes but don't know how to do it for lists?

listname=listname.fillna(0)

This isn't working.

Answer 1

You can convert to a pandas series and back to a list

pd.Series(listname).fillna(0).tolist()

Consider the list listname

listname = [1, np.nan, 2, None, 3]

Then

pd.Series(listname, dtype=object).fillna(0).tolist()

[1, 0, 2, 0, 3]
