[5 marks]Find the error: for i in range(5) print(i)
[3 marks]Explanation:Missing colon ':' at the end of the for loop statement.
Find the error: d = {1: 'a', 2: 'b'} print(d[3])
[3 marks]Explanation:The key 3 does not exist in the dictionary.
Predict the output: lst = [1, 2, 3] lst.append([4, 5]) print(len(lst))
[3 marks]Explanation:The list [4, 5] is appended as a single element, so the list becomes [1, 2, 3, [4, 5]].
Predict the output: lst = [1, 2, 3] lst.append([4, 5]) print(len(lst))
[3 marks]Explanation:The list [4, 5] is appended as a single element, so the list becomes [1, 2, 3, [4, 5]].
