Here’s a seemingly simple question: given a chunk of multi-line text, how do you split it and return an array whose members are the constituent lines of the text? Hopefully, your first instinct is to reach for some sort of standard-library function, maybe something like the splitlines() method of Python’s str type. Because it turns out this “simple” question is actually pretty complex to answer!…

But one quick note to start with: this is not really “introducing”…

There s a concept that I ve heard called by a lot of different names, but my favorite name for it is the Highlander problem , which refers to the catchphrase of the campy-yet-still-quite-fun Highlander movie/ TV franchise.
