only when all the elements are Truthy.
Truthy != True.
all essentially checks whether bool(something) is True (for all somethings in the iterable).
>>> "?" == True
False
>>> "?" == False # it's not False either
False
>>> bool("?")
True

'?' and '!' are both truthy since they are non-empty Strings.
There's a difference between True and "truthy". Truthy means that when coerced, it can evaluate to True. That's different from it being == to True though.

r/learnpython on Reddit: Is there a list of every Python function out there?
February 12, 2023 -
I recently learnt that stuff like .strip(), .title(), exists, which got me interested to learn about all these little bonus gimmicks about Python that I could use in my everyday tasks or to improve functionality in my code.
As of now I know that https://docs.python.org/3/library/functions.html exists but there isn't the functions mentioned above within that list. Is there another list of all these functions including those mentioned out there? Thank you

That's because the ones you mention are methods of the str type, not builtin functions. You can find the methods of all standard types here .

The link you provided lists all the built-in functions Python has that you don't need to import explicitly - including some classes that were made to look like functions. There aren't any "hidden" ones. What you were describing stuff like .strip(), .title(), exists are, specifically, methods of the str-class, so it would be more appropriate to call these str.strip and str.title as they're bound to the class and are, in fact, not free functions. Every class has methods, some more than others. If you want to learn more about individual classes, I recommend reading up their entries in the documentation. Of course, the standard library has all kinds of classes and functions not mentioned here, from functools.partial to pathlib.Path, so you'd do well to explore a little.

If the goal is:
Check that all elements of a list are not present in a string.
The pattern should be: all(s not in my_string for s in input_list)
l = ["abc","ghi"]
s1 = "xyzjkl"
s2 = "abcdef"
print(all(s not in s1 for s in l)) # True
print(all(s not in s2 for s in l)) # False

You need a list of True, False. But you were simply getting the matched items, so when you do an all on Truthy values you will get True. Instead do:
all([x not in s1 for x in l])
all([x not in s2 for x in l])
or just without list comp, because all accepts an iterable.
all(x not in s1 for x in l)
all(x not in s2 for x in l)
