python - 根据句子中的单词对多个句子进行句子分类

Question

data = ["my web portal is not working","online is better than offline", "i like going to pharmacy shop for medicines"]
words = ["web", "online"]

我想迭代句子并检查列表单词中是否存在任何单词。如果是，我想要每个句子都有一个类别，其他类别为“其他”。如果我从单词列表中给出单个单词，它就可以工作，但我想在单次运行中检查所有单词。

b = []
def ch_1(x,y):
    for i in x:
        if y in i:
            b.append("web")
        else:
            b.append("others")
    return b

出现错误:

in ' requires string as left operand, not list

Answer 1

此代码适用于words中任意数量的单词和data中的句子:

data = [
    "my web portal is not working",
    "online is better than offline",
    "i like going to pharmacy shop for medicines"
]

words = ["web", "online"]


def ch_1(words, data):
    categories = {sentence: [] for sentence in data}
    for sentence in data:
        for word in words:
            if word in sentence:  # and categories[sentence] == [] ((if you want exactly one category for each sentence))
                categories[sentence].append(word)
    for sentence in categories:
        if categories[sentence] == []:
            categories[sentence].append('others')
    return categories

print(ch_1(words, data))

{
'i like going to pharmacy shop for medicines': ['others'],
'online is better than offline': ['online'],
'my web portal is not working': ['web']
}
