缺失值指数据集中某些变量的值有缺少的情况,缺失值也被称为NA(not available)值。在pandas里使用浮点值NaN(Not a Number)表示浮点数和非浮点数中的缺失值,用NaT表示时间序列中的缺失值,此外python内置的None值也会被当作是缺失值。需要注意的是,有些缺失值也会以其他形式出现,比如说用NULL,0或无穷大(inf)表示。
In the world of data manipulation and analysis, handling missing values is a crucial task.Pandas, a widely-used Python library, allows us to efficiently manage missing data. One common approach to dealing with missing values involves using dictionaries to map and replace these values. In this ar...
