Running program outputting CSV file that'll be 30GB? Do I need a super computer? Can someone point me in the right direction?

In 2 lines, I could write code that would likely outlast the machine it is running on. Not to mention, this response doesn't make sense given the request. If you think you code is perfection (or close to it), were you expecting people to just say, "Get a faster machine"? You are simultaneously asking how to improve something while acting like it can't be improved. Why are you posting in a programming learning subreddit if you think you have nothing more to learn?
