Note the duality:

any(x for x in y) == not all(not x for x in y)
all(x for x in y) == not any(not x for x in y)

or alternatively

not any(x for x in y) == all(not x for x in y)
not all(x for x in y) == any(not x for x in y)

as a consequence of De Morgan’s theorems.

"all" is "and" in disguise, "any" is "or" in disguise.

Been learning Python and writing programs the past couple of months and your videos have been tremendously helpful.

I'm skeptical, because it's going to do exactly what the for loop is going to do. However the for loop is going to be optimized with C. Any or All will make your code slower

Logic gates emulating logic gates, love it

[pattmehta]

very useful pat, found it today - there is also a sum built-in; sum also works with a list of booleans :)

[jovaraszigmantas]

Hey, quick question I know the all method is shorter to write but isn't the for loop faster as sometimes it doesn't have to loop through the whole loop. All and any are powerful but I would only use them if the list is already contains only booleans or similar cases?

[raminmousivand]

Your videos are fantastic. Thanks for such tips :)

[vanya]

Note that "any" and "all" returns true if you will pass an empty list to it.

[WhyNotProgram]

Good stuff! Gotta love when you can make code shorter.

[muuur]

I knew both functions, but i never expect the actual usage was something like this, thanks so much

[fastrockstar]

Wow. Somehow I always forget stuff like that and do it like I used to do it all the time. Nice work Patrick!

[ninjanape]

This is awesome. I will just suggest you use a better quality microphone for videos.

[cipherxen]

These python junkies will go to any length to make everything one liner, whatever the cost maybe.

[piotr]

So generator is faster then simply any(numbers) ?

[Vlakoosh]

God I wish you could save youtube shorts

[NikkiMcMistie]

wow so many hidden utilities in this language

[MrJonas]

How do you keep all that handy stuff in your mind?

[imlazy]

Is any or all faster than manual looping?

[Shyam_Mahanta]

Still lacking in terms of javascript's some and every method
