Rich, You got an overly general reply to a question many of us may not understand.
You have not hinted at how the two files are organized, perhaps with an example. There are several general solutions that may apply. Some involve reading in both files into data structures and perhaps linking them together in some way such as a data.frame or binary tree. You can then process individual request in memory/ The second should be straightforward as long as text is text. If the first file tells you to search for XYZ then you search the second file for XYZ and read in whatever is associated with it and do your thing. Without a bit more specific detail, you may not get more than a suggestion as to how to read in files. -----Original Message----- From: Python-list <python-list-bounces+avi.e.gross=gmail....@python.org> On Behalf Of Rich Shepard via Python-list Sent: Monday, January 29, 2024 12:38 PM To: python-list@python.org Subject: RE: Extract lines from file, add to new files On Mon, 29 Jan 2024, Rich Shepard via Python-list wrote: > No, I hadn't ... but I am reading it now. Perhaps I missed the answer to my question when reading the io module. It explains how to open/write/read files of text and binary data, not passing a variable's value from one file to a place-keeper in another file. I'll keep searching for a solution.
