fillna pandas with mode code example

Example 1: fill na with mode and mean python

cateogry_columns=df.select_dtypes(include=['object']).columns.tolist()
integer_columns=df.select_dtypes(include=['int64','float64']).columns.tolist()

for column in df:
    if df[column].isnull().any():
        if(column in cateogry_columns):
            df[column]=df[column].fillna(df[column].mode()[0])
        else:
            df[column]=df[column].fillna(df[column].mean)

Example 2: dataframe fillna with 0

df['column'] = df['column'].fillna(0)

Example 3: python fillna with mode

data['Native Country'] = data['Native Country'].fillna(data['Native Country'].mode()[0])

Example 4: 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.
