问Python -如何从三个数据集中查找不匹配的记录

EN

indexes = df1[(df1[TARGET_COLUMN]!=df2[TARGET_COLUMN]) | (df1[TARGET_COLUMN]!=df3[TARGET_COLUMN])].index

def compare_indexes(x):
    index = x.name
    for column_name in df1.columns.values:
        if not (x[column_name] == df2.iloc[index,:][column_name] == df3.iloc[index,:][column_name]):
            return False
    return True


df1["match"] = df1.apply(compare_indexes, axis=1)
indexes = df1[df1["match"]==False].index

merged_df = pd.merge(df1, df2, how='outer', on='[your index]').merge(df3, how='outer', on='[your index]')

result = merged_df.loc[~merged_df.index.isin(merged_df.dropna().index)]
