列表解析是Python中一种简洁且高效的处理列表的方法,可以用于实现简单的isin功能: # 定义两个列表 list1 = ['Alice', 'Bob', 'Charlie', 'David'] list2 = ['Alice', 'Bob'] 使用列表解析检查list1中的元素是否在list2中 result = [item for item in list1 if item in list2
此过程可以通过以下表格更清晰地展示: 以下是Python中isin的简单实现示例: defcustom_isin(data:list,values:list)->list:return[iteminvaluesforitemindata]names=['Alice','Bob','Charlie','David']selected=['Alice','David']print(custom_isin(names,selected)) 1. 2. 3. 4. 5. 6. CustomFunctionDataF...

这个错误的原因是,你尝试在一个列表(list)对象上调用.isin()方法。然而,.isin()方法是Pandas库中的Series对象或DataFrame对象的方法,用于过滤数据,而不是Python内置列表(list)对象的方法。因此,当你尝试在列表对象上调用这个方法时,Python会抛出AttributeError。
