我已经实现了这个简单的功能,以便搜索句子中的特定单词:
import re
def word_in_text(word, sentence):
word = word.lower()
sentence = sentence.lower()
match = re.search(word, sentence)
if match:
return True
return False
但这不适用于全世界。例如在句子中:
a = "RT @Kaus_Pandey17: Wrote some words about new #Liverpool"
我得到了这个奇怪的结果:
word_in_text('wrote',a)
False
word_in_text('Wrote',a)
False
word_in_text('some',a)
True
word_in_text('#Liverpool',a)
False
word_in_text('17',a)
True
word_in_text('Pandey',a)
False
word_in_text('RT',a)
False
word_in_text('some',a)
True
有一些不正确的False返回,我不明白为什么
谢谢

您的变量不能与参数具有相同的名称。将变量名称更改为唯一的名称,如下所示:
import re
def word_in_text(word, sentence):
wo = word.lower()
sen = sentence.lower()
match = re.search(wo, sen)
if match:
return True
return False
print(word_in_text('Liverpl','RT @Kaus_Pandey17: Wrote some words about new #Liverpool'))
