我已经编写了以下代码，
def Key_words(y):
if(any(bool(re.search(r'b'+x+r'b', ''.join(y).lower()))) for x in keywords):
return("Yes")
else:
return("No")
Key_words(Text)
其输出为Yes但是输出应该是No，因为文本中没有匹配的关键字。
请帮我得到正确的输出。
这是使用re.search的一种方法。
例如：
import re
keywords=["just checking to see if you are there so we can continue.", "please let me know if you're receiving my responses or i will need to end our session", "our chat session is now ending. thanks for choosing at&t! we appreciate your business."]

def Key_words(y):
if re.search("(" +"|".join(keywords) + ")", r"n".join(y), flags=re.IGNORECASE):
return("Yes")
else:
return("No")
print(Key_words(Text))
您可以使用in(更快更简单(：
keywords=["just checking to see if you are there so we can continue.", "please let me know if you're receiving my responses or i will need to end our session", "our chat session is now ending. thanks for choosing at&t! we appreciate your business."]

def Key_words(y):
text = ' '.join(y).lower()
print(text)
for key in keywords:
if key.lower() in text:
return("Yes")
return("No")
print(Key_words(Text))
在这里，我们将只在文本中没有一个关键字的情况下迭代每个关键字。在所有其他情况下，我们都会有更好的表现。
有什么原因不能做这样简单的事情吗：
Keywords=["just checking to see if you are there so we can continue.", "please let me know if you're receiving my responses or i will need to end our session", "our chat session is now ending. thanks for choosing at&t! we appreciate your business."]

代码的问题是这一行放错了括号：
if (any(bool(re.search(r'b'+x+r'b', ''.join(y).lower()))) for x in keywords):
在您的情况下，表达式re.search(r'b'+x+r'b', ''.join(y).lower())的计算结果始终为None，因此上述if语句可以重写为：
if (any(bool(None)) for x in keywords):
现在，表达式(any(bool(None)) for x in keywords)返回生成器，该生成器针对keywords中的每个x生成表达式any(bool(None))。表达式本身在语义上是无效的，因为any需要一个可迭代的，而不是bool作为其参数，因此这将自己引发一个TypeError。
然而，表达式any(bool(None))永远不会被求值，因为它不是必需的。if语句立即成功，因为它的参数是生成器(而不是bool(，并且生成器在转换为bool时总是计算为True，无论它们生成什么。
因此，要修复这种行为，您需要像这样移动括号：
if any(bool(re.search(r'b'+x+r'b', ''.join(y).lower())) for x in keywords):
