问题 I have the code below. I'm trying to remove two strings from lists predict strings and test strings if one of them has been found in the other. The issue is that I have to split up each of them and check if there is a "portion" of one string inside the other.

ValueError: list.remove(x): x not in list I get the above error though and I am assuming this is because I can't
