BEWARE SubDeskTop = Path.joinpath (Desktop, "/subdir") won't work. The I/O time will completely swamp the line-parsing time, so as long as the implementor didn't do something horribly stupid in the buffering, it will be just as fast (and possibly even faster than trying to guess at a good buffer size yourself, if you think 10000 is a good choice). The os.path.join method continues from the absolute path component we have specified (/Users/James/tutorials). OS module in Python provides functions for interacting with the operating system. (Also, the fact that fileinput closes each file as soon as it's done means there's no need to with or close each one, but that's just a one-line savings, not that big of a deal.).
