In this example, it’s important to note the following: I’ve used print to write to the file. This automatically adds newlines after the strings I supply.

I use sequence unpacking on the opened file, putting each line in a separate variable. (This isn’t exactly common practice because you usually won’t know the number of lines in your file, but it demonstrates the “iterability” of the file object.)

I close the file after having written to it, to ensure that the data is flushed to disk. (As you can see, I haven’t closed it after reading from it. Sloppy, perhaps, but not critical.)
