现在，我想提取包含 "Project", "Teamsize " 这样的词的部分摘要 不提取其他摘要部分。 我在下面尝试过这段代码，它提取了两个摘要内容

import re
import os
with open ('9.txt', encoding='latin-1') as infile, open ('d.txt','w',encoding='latin-1') as outfile :
    copy = False 
    for line in infile:
        if line.strip() == 'summary':
            re.compile('\r\nproject*\r\n')
            copy = True
        elif line.strip() == "summary":
            copy =False 
        elif copy:
            outfile.write(line)
        #fh = open("d.txt",'r')
        contents = fh.read()
        len(contents)

我希望保存一个包含内容的文本文件作为 d.txt

Answer 1

要提取所有包含您感兴趣的单词的summary 部分：

split_on = 'summary\n\n'
must_contain = ['Project', 'Team Size']

with open('9.txt') as f_input, open('d.txt', 'w') as f_output:
    for part in f_input.read().split(split_on):
        if all(text in part for text in must_contain):
            f_output.write(split_on + part)

Answer 2

这里的第二个条件语句永远不会运行，因为它与第一个条件相同。这意味着在summary 的第一个实例之后，副本将始终为True。

if line.strip() == 'summary':
    re.compile('\r\nproject*\r\n')
    copy = True
elif line.strip() == "summary":
    copy =False 

我建议使用一个语句来获取“摘要”标签（我假设这些是注释块的开始/结束） - 并切换 copy。

要切换布尔值，您可以简单地将其设置为自身的倒数：

 a = True
 a = not a
 # a is now False

例如：

 if line.strip() == 'summary':
    copy = not copy
 elif copy:
    outfile.write(line)
