Cool Set Features No One Told You About In Python

[@maxweinstein1537]

Thumbnail has a typo: symmetric difference and intersection should be swapped

[@MateuszAdamowski-k8b]

Also:
print(2 in a)
to check if given element is present in a set

[@watchmakerful]

Are a -= b and a.difference_update(b) the same in terms of memory and CPU time?

[@IonicMC]

***I think***
Both are turned to "CALL set.diffrence_update(a, b)" in byte code (not this, but just the same meaning)

[@rondamon4408]

a: set[str] = {"cool", "useful", "great" }

[@ledinhthai69]

Oh my god! I saw your face now although I have listened to your lessons alot. Thanks for help

[@samoylov1973]

a |= b
will update a, sort of
a = (a | b)
but in shorter form

[@ivanheffner2587]

The “syntactic sugar” operators make sense if you think about it in terms of bitwise operators. & is in both; ^ is in one or the other but not both; | is in either; AND, XOR, OR.

Knowing this would have helped me in my Discrete Math class lol

[@elizabethkirby1782]

Nice to see your face -- not important for the info, but nice just the same. :-). Also, thanks very much for the videos.

[@CultureofSpeech]

By the way, I'm looking forward your newt videos on "one liners" in python script.
Kinda regards and respect.

importlib module (usecases)
and __import__ function

[@thetdg]

In the thumbnail, ^ and & got interchanged

[@Indently]

Thank you, I’ll fix it as soon as I get the chance!

[@djtomoy]

[@danielputter]
