利用pandas 处理缺失值

处理缺失值

def missing_values(dataframe):
    missing_ratio = (dataframe.isnull().sum() / len(dataframe))*100
    missing_ratio = missing_ratio.drop(missing_ratio[missing_ratio == 0].index).sort_values(ascending=False)
    missing_count = dataframe.isnull().sum()
    missing_count = missing_count.drop(missing_count[missing_count == 0].index).sort_values(ascending=False)
    info = pd.DataFrame({'Missing Ratio': missing_ratio, 'Missing Count': missing_count})
    return info
