从最好理解的来: 方法一:pandas没有isnotin,我们自己定义一个。 a.定义函数: b.运用函数: 方法二:使用列表的not in方法 + 简单函数 这种方法类似于第一种,不过更简洁。 方法三:使用merge a.先将不想要的筛选出来成一个DataFrame b.将两个DataFrame使用merge合并 c. 通过isnull筛选空值,筛选出我
4. m_notin=m[~m.c.isin([3,4])] print('m not in is\n',m_notin) 1. 2. 3. m not in is a b c 1 4 5 6 2 7 8 9 3 10 11 12 1. 2. 3. 4. 5.
首先,直接在pandas库中查找isnotin功能是不存在的,为此,我们需通过编程手段实现这一需求。以下是几种可选的实现方式,旨在简化数据筛选过程,提高效率。方法一:定义自定义函数,运用函数进行筛选。这包括定义一个函数,然后将数据集中的特定列转换为列表,进一步转换为集合,使用集合的差集操作来找出不在...

根据上句“Pandas once lived in a few parts of Asia, including(包括) Vietnam and Burma.” 熊猫曾经生活在亚洲的一些地区,包括越南和缅甸。可知本段讲述熊猫的居住地,所以B项“Now they live in some parts of China. 现在它们住在中国的一些地方。”符合语境,故选B。【小题2】根据上句“Pandas spend ...
