U.append(i)
A = [8,9,10,11,12,16,17,22,25]

1Loop through `A`, calling `U.remove()` with each element. – Barmar Oct 21 '21 at 19:51

What do you mean "extract A values" from the other list? You already have the values in A. Why do you need to extract the same ones from U? – ddejohn Oct 21 '21 at 19:51

do you mean you would like a version of the list U without any of the items in A? – barker Oct 21 '21 at 19:51

If order isn't important, you can convert them to sets and use subtraction. – Barmar Oct 21 '21 at 19:53

Use a list comprehension:
[item for item in U if item not in A]
