如何使用python脚本以特定的间隔连接行？你知道吗

我正在为比赛做文本分析。但这也有问题。在html扩展文件<p>1. *</p>中，问题以数字开头，后跟“.”行在下面给出的html扩展文件中。你知道吗

<p>1. Arrange the following words as per the order in dictionary.</p> <p>1. Inappropriate</p> <p>2. Inappeasable</p> <p>3. Inaptitude</p> <p>4. Inapplicable</p> <p>5.

Answer 1

最后，我能够为我提出的问题编写代码。代码如下所示。。你知道吗

import sys
import re
answerstart = re.compile('<p>\([12345]*\) ')
uestionstart = re.compile('^<p>[0123456789]*\. ')
data = open(sys.argv[1]).readlines()
allq = []
flag = False
for  line in reversed(data):
   if answerstart.match(line):
      if '<p>(1) ' in line:
        allq.append('\n'+line)
      else:
        allq.append(line)
   elif line.startswith('<p>Answer '):
      flag = False
      allq.append('\n'+line.rstrip())
   elif questionstart.match(line):
      if '<p>1. ' in line:
         allq.append(line.rstrip())
         flag =  True
      else:
         if flag == True:
            allq.append('\n'+line.rstrip())
         else:
            allq.append(line.rstrip())
            flag = False
   else:
      allq.append(line)
new = []
for line in reversed(allq):
   new.append(line)
print "".join(new)

但是在这段代码中有一个问题是，这将只适用于我在上面的问题中发布的格式。你知道吗
