我编写了一个函数来从文件中提取模式，但它不能正常工作。为什么？

我在Python中的代码：

import re

f = open('quran_final.txt','r')
r = open('q.txt','w')
p = re.compile('ROOT:(?P<root>[^ "]+)')
for line in f:
    root = p.findall(line)
    if(root):
        for word in root:
        print word
    else:
        print ' '

我认为问题出在“检查”中，但是我应该如何更改呢？

我的文本文件示例：

f:CONJ+ POS:V IMPV ROOT:Akl 2MP  
POS:LOC LEM:Hayov ROOT:Hyv  
POS:V PERF ROOT:$yA 2MP  
POS:ADJ LEM:ragad ROOT:rgd M INDEF ACC

如果我理解正确，您需要在模式中包含 endline

p = re.compile('ROOT:(?P<root>[^\s]+)')

缩进 - 打印单词需要再缩进四个空格。根应该是：

root = re.findall(p, line)
