now, i would like to extract section summary which contains words like "Project", "Teamsize " without extracting the other summary section. i have tried this code below, it extracts both summary content

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)

and i'm expecting a text file as d.txt to saved which contains content

回答1:

To extract all summary sections that contain the words you are interested in:

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)

回答2:

The second conditional statement here will never run, as it has an identical condition to the first one. Meaning copy will always be True after the first instance of summary.

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

What I'd recommend is having one statement that picks up the "summary" tags (I assume these are meant to be start/end of comment blocks) - and toggle copy.

To toggle a boolean, you can simple set it to the inverse of itself:

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

For example:

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