如何使用Python检查在文本文件中使用findall？

Question

我写了一个从文件中提取模式的函数，但它没有正常工作。为什么？你知道吗

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 ' '

我想问题出在“支票”上，但我该怎么改呢？你知道吗

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  
wa+ POS:V IMPV ROOT:dxl 2MP  
Al+ POS:N LEM:baAb ROOT:bwb M ACC  
POS:N LEM:saAjid ROOT:sjd MP INDEF ACC  
wa+ POS:V IMPV ROOT:qwl 2MP  
POS:N LEM:HiT~ap ROOT:HTT F INDEF NOM  
POS:V IMPF ROOT:gfr 1MP MOOD:JUS

POS:V PERF ROOT:kwn SP:kaAn 3MP  
POS:V IMPF ROOT:fsq 3MP  
POS:V PERF (X) ROOT:sqy 3MS  

Answer 1

如果我理解正确的话，你需要在你的模式中加入结束线

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

Answer 2

缩进-打印字需要再缩进四个空格。根目录应为：

root = re.findall(p, line)
