如何检查字符串列表中的字符串是否在pandas dataframe列中

尽管您说循环可能太慢，但由于列表的范围，它似乎是最有效的方法。试图使其尽可能简单。可以根据您的需要随意修改打印语句。

text = 'Bad Word test for Terrible Word same as Horrible Word and NSFW Word and Bad Word again'
bad_words = ['Bad Word', 'Terrible Word', 'Horrible Word', 'NSFW Word']

length_list = []

for i in bad_words:
    count = text.count(i)
    length_list.append([i, count])


print(length_list)

输出：

[['Bad Word', 2], ['Terrible Word', 1], ['Horrible Word', 1], ['NSFW Word', 1]]

另外，您的输出作为字符串可以是：

length_list = []

for i in bad_words:
    count = text.count(i)
    print(i + ' count: ' + str(count))

输出：

Bad Word count: 2
Terrible Word count: 1
Horrible Word count: 1
NSFW Word count: 1
