Other values in the Street Number column also change, such as the count and mean. The difference is not huge due to only a few values being 0. However, with more significant amounts of wrongly labeled data, the differences in metrics are also more noticeable. Drop Missing Values The easies...
duplicate_rows = matches.index.get_level_values(1) print(census_B_index) 5. 我们可以使用index属性访问数据框的索引。由于这是一个多索引数据框,因此它返回一个多索引对象,其中分别包含来自census_A和census_B的行索引对。我们希望提取所有census_B索引,因此我们将其与get_level_values方法链接起来,该方法包含...
