df["column_name"].isin(set or list-like)->Series:常用于判断df某列中的元素是否在给定的集合或者列表里面。 三、缺失值、重复值检查与处理 1、空表检查: Series/DataFrame.empty()->Ture or False.Note:如果 Series/DataFrame 仅包含 NaN,它仍然不被视为空,所谓空表就是只有列标签(行标签),没有任何数...
Pandas是一个强大的数据处理和分析库，提供了多种数据结构和功能，其中最重要的基础结构包括DataFrame、Index、Column、Axis和缺失值。下面将介绍这些概念和相关操作。1. DataFrameDataFrame是Pandas中最重要的数据结构之一，可以看作是一种二维表格数据结构，类似于Excel中的电子表格。如下图所示，一个表格在excel和pandas...
As we can see in the output, the Series.str.contains() function has returned a series object of boolean values. It is true if the passed pattern is present in the string else False is returned. Example #2:Use Series.str.contains a () function to find if a pattern is present in the...
