我想在“res =”之后提取数据。所以，我只需要这些数据：'file：// pvr / 2902F60E'

if "res=" in last_event:

print "True"
m = re.search('res=\W\S+', last_event)
m.group(0)
print m

输出结果为：

真＆lt; _sre.SRE_Match对象位于0x0268D5D0＆gt;

任何帮助都将不胜感激。

Answer 1

只需使用()捕获群组（m.group(0)打印整个字符串，您不需要res=或文字前面的前导空格

m = re.search(r'res=\W(\S+)', last_event)
if m: print(m.group(1))

顺便说一下，我怀疑在你的整套线路上应用re.findall，所以你得到一个匹配列表而不是逐行扫描，对你的使用来说比对匹配对象＆amp;提取

import re

print(re.findall(r'res=\W*(\S+)', lines))

（也容忍=之后的非空格

）

Answer 2

你可以去：

import re

rx = re.compile(r"res=\s*'([^']+)'")

try:
    m = rx.search(your_string)
    filename = m.group(1)
    print(filename)
except:
    print("Not found")
