获取正则表达式匹配的字符串？

Question

我为reddit bot获取了这段代码：

match = re.findall(r"(?i)\bword1\b|\bword2\b|\bword3\b", comment.body)

匹配几个单词。如何打印匹配的单词？

Answer 1

看看这个例子。这可能会对你有所帮助

import re
f=open('sample.txt',"w")
f.write("<p class = m>babygameover</p>")
f.close()
f=open('sample.txt','r')
string = "<p class = m>(.+?)</p>"
pattern = re.compile(string)
text = f.read()
search = re.findall(pattern,text)
print search
