Exam PCEP-30-02 topic 1 question 20 discussion

Let's step through this code to understand what's happening: We start with my_list = [1, 2] The loop for v in range(2): will run twice, with v taking values 0 and 1. In each iteration, we're using my_list.insert(-1, my_list[v]): insert(-1, ...) means insert at the second-to-last position my_list[v] is the element we're inserting Let's go through the iterations: First iteration (v = 0): We insert my_list[0] (which is 1) at index -1 my_list becomes [1, 1, 2] Second iteration (v = 1): We insert my_list[1] (which is now 1) at index -1 my_list becomes [1, 1, 1, 2] After the loop, we print my_list Therefore, the output will be: [1,1,1,2]

my_list = [1,2] for v in range (2): my_list.insert(-1,my_list[v]) >>> loop 1: v=0 >> insert my_list[0] in the position my_list[-1] >> my_list = [1,1,2] >>> loop 2: v=1 >> insert my_list[1] in the position my_list[-1] >> my_list = [1,1,1,2] print(my_list) >>>> [1,1,1,2] (B)

b is the correct answer
