split cuts up any old text string, like
mary had a little lamb and turns it into a formal list, like
["mary", "had", "a", "little", "lamb"], with each word made into an indexable (numerically anyway) item in a list, via the format of
stringofwords.split(" "). I’m not toooootally square on the quotes in the formatting of the use of
split, but I can punch it in well enough til I grok it fully.
join depends on the same structure of
listofitems.join(" ") to de-string-ify it. Handy!
There’s a bit also with, hmm, how do you call it, positional list comprehension, maybe? For example in the previous given list, the
["mary", "had", "a", "little"} et cetera, position
0 is the very first one,
mary, where position
-1 is the very last,
This was a good one! I think the exercises will stay challenging through the next thirteen : )
