how to fillna in all columns with their mean values
# if you want to fill NaN in a single column with its mean value
df['col'].fillna(df['col'].mean(), inplace=True)
# if you want to fill NaN in more than one columns with their respective mean values
df.fillna(df.mean(), inplace=True)fillna pandas inplace
When inplace = True , the data is modified in place, which means it will return nothing and the dataframe is now updated. When inplace = False , which is the default, then the operation is performed and it returns a copy of the object. You then need to save it to something.Copyright © 2021 Codeinu
