Question
What is the output of the following?x = ['ab', 'cd']for i in x: x.append(i.upper())print(x) [‘AB’, ‘CD’] [‘ab’, ‘cd’, ‘AB’, ‘CD’] [‘ab’, ‘cd’]none of the mentioned
Solution
This code will result in an infinite loop. The reason is that you're trying to append to the list 'x' while iterating over it. This means that the loop will never reach the end of the list, because you're constantly adding new elements to it. So, none of the mentioned options is correct.
