Identifing this dataset for sanitising

I am beginner here starting with data science for analytics. I am trying to figure out what data set this is and how to read it from python. I have an idea of the steps but not sure how to code it in python.

1. Open read the file
2. Search for keywords based on another file
3. If keyword found, search for Term from that line up and copy value of id: which is below it. If more than one keyword is found copy their id value with a comma.
4. Close the file If anyone can direct me to any tutorial that would help me here. I would appreciate it. I came across a lot of them but those data sets are tables and columns.
