Question
1) ListBasics.py A) (10 Points) Write a for loop that iterates over a list of numbers num_list and prints the numbers in the list whose square is divisible by 8. For example, if num_list is [2, 3, 4, 5, 6, 7, 8, 9], then the numbers 4 and 8 should be printed.
B) (10 Points) Given list_a = [30, 1, 12, 14, 10, 0] a) How many elements are in lst? b) What is the index of the first element in list_a? c) What is the index of the last element in list_a? d) What is list_a[2]? e) What is list_a[-2]?
C) (20 Points) 10.6 Given list_1 = [3, 1, 2, 4, 0], what is the return value of each of the following statement? a) [x for x in list_1 if x > 1] b) [x * x for x in list_1] Using list comprehension, create the following lists c) [10, 8, 6, 4, 2] d) [0, 2, 4, 6, 8]
D) (10 Points) What are list_x and list_y after the following lines of code? List_x = [1, 43] List_y = [x for x in list_x] List_x[0] = 22
