提取文本文件中两个字符串之间的值 [英] Extract Values between two strings in a text file

问题描述

假设我有一个包含以下内容的文本文件

Lets say I have a Text file with the below content

fdsjhgjhg
fdshkjhk
 Start
     Good Morning
     Hello World
 End
dashjkhjk
dsfjkhk
Start
  hgjkkl
  dfghjjk
  fghjjj
Start
   Good Evening
   Good 
End

我编写了以下代码:

infile = open('test.txt','r')
outfile= open('testt.txt','w')
copy = False
for line in infile:
    if line.strip() == "Start":
        copy = True
    elif line.strip() == "End":
        copy = False
    elif copy:
        outfile.write(line)

我的结果在文件外:

     Good Morning
     Hello World
     hgjkkl
     dfghjjk
     fghjjj
     Good Evening
     Good

我的问题是我只想在开始和结束之间取数据，而不要在开始和开始或结束和结束之间取数据

My problem is I want to take just the data between start and end but not between start and start or End and End

推荐答案

大问题！这是一个桶问题，每个起点都需要一个终点.

Great problem! This is a bucket problem where each start needs an end.

之所以得到结果，是因为有两个连续的开始".

The reason why you got the result is because there are two consecutive 'Start'.

最好将信息存储到某个地方，直到触发"End"为止.

It's best to store the information somewhere until 'End' is triggered.

infile = open('scores.txt','r')
outfile= open('testt.txt','w')
copy = False
for line in infile:

    if line.strip() == "Start":
        bucket = []
        copy = True

    elif line.strip() == "End":
        for strings in bucket:
            outfile.write( strings + '\n')
        copy = False

    elif copy:
        bucket.append(line.strip())
