Question

我需要在文本文件中匹配一些字符串，并希望返回匹配的行。比方说，我在2D数组中有如下字符串：

[['Shoo-Be-Doo-Be-Doo-Da-Day', 'Henry Cosby'],
 ['My Cherie Amour (song)', 'Stevie Wonder'],
 ["Signed, Sealed, Delivered I'm Yours", 'Stevie Wonder]]

这样我就可以在文本文件中搜索字符串，例如：['Shoo-Be-Doo-Be-Doo-Da-Day', 'Henry Cosby'] [''，''] [''，''] ....在file.txt中，这些行看起来像这样：

abcd Shoo-Be-Doo-Be-Doo-Da-Day skakk gkdka kkhhf Henry Cosby.
gfigka Stevie Wonder hfkhf hghhg fghh My Cherie Amour.
fhsgs hlghhg  Henry Cosby Shoo-Be-Doo-Be-Doo-Da-Day gkgkl.

然后我应该用标记匹配字符串返回整行。对于1D阵列，以下代码有效：

def search(word, sentences):
    return[i for i in sentences if word in i]

对于上面的2D阵列，如何继续？

Answer 1

这个怎么样：

def search(sentences, words):
  return [s for s in sentences if all([w in s for w in words])]

Answer 2

这应该有效：

def search(patterns, sentences):
    for sentence in sentences:
        if any(all(p in sentence for p in pattern) for pattern in patterns):
            yield sentence

matched = list(search(['Shoo-Be-Doo-Be-Doo-Da-Day', 'Henry Cosby'],
                      sentences))

在Python中匹配行
