Really nice demonstrations of the key features of Python in relation to 'Sets'. Also, thanks for the quick
reminders of definitions of the key statistics terms.

Quick tip ... if you are following along and want the path to where YOU stored a file, store it in the same folder as the rest of your VSC files so you can see it, then right click file and 'copy path' (shortcut shift+alt+c). Will save you having to get it through explorer.

WiseOwl Team - you killed it with the stripping quotation from punctuation. although you didn's explain the maketrans method, but that was very helpful. I decided to be a member to support you guys b/c I know exactly the amount of efforts and time you invest to explain these intricate subjects.
Q? = would the Egg membership get me access to new uploads (for instance - can I have access to Classes if I become Egg member or I need to be a chicken (you know what I mean 🙂)

THANK YOU!!

Great video thanks!

Let's say I want to get rid of the weird character that appears in front of Arsenal. How would I go about it? I have spotted the same issue, working with the files from previous videos

Great video! I just think there's a tiny mistake made in the unique letter counting. 21 characters <> 21 letters. I think it's 19 letters, as 'a' and 'A' are counted twice and a single space ' ' is also not a letter.
