I have read a file. Now I have all these lines of strings. I need to extract specific lines. These lines are between two lines with a specific string in them. There is no set amount of lines between them. Also, I have to match the two lines. For example, There may be the string in the first line, but there is no match, so I will get the same string after a number of lines. Then I have to see if that line has the match. I have no clue how to do this.

def main():
infile = open(“file.txt”, “r”)
outfile = open(outfile.txt”,”w”)
for line in infile:
if “theString” in line:
break
for line in infile:
if “different string” or “anotherString” in line:
break
outfile.write(line)

 
Hi

As indentation is mandatory in Python, please start a new thread where you post your code between [tt][ignore]
Code:
[/ignore][/tt] and [tt][ignore]
[/ignore][/tt] TGML tags to preserve formatting.

Then click the [navy]Inappropriate post? If so, Red Flag it![/navy] at the bottom of your starting post here and ask forum management to delete this thread as you already posted a cleaned up version of it.
