Question 10

How do you check if a list is empty?

list == 0 bool(list) len(list) type(list)

Question 11

What will this print? items = [1, "apple", 3.5] for item in items: print(type(item))

Only <class 'int'> Only <class 'str'> Different data types Error

Question 12

If numbers exist If list is empty If a list is inside another list If items are strings

Question 13

1 2 3 Error

Question 14
