• [1, 3, 5, 7, 9]
• [1, 2, 4, 6, 8]
• [2, 4, 6, 8]

2. What will be the output of the following code snippet?

a=[1,2,3,4,5]

print(a[3:0:-1])

• [2, 1]
• [3, 2]
• [5, 4]
• [4, 3]

4. The below code is iterating over a nested Python list. What will be the output?

arr = [[1, 2, 3, 4],

[4, 5, 6, 7],

[8, 9, 10, 11],

[12, 13, 14, 15]]

for i in range(0, 4):

print(arr[i].pop())

• 4, 7, 11, 13
• 3, 6, 9, 12
• 1, 4, 8, 12
• 4, 7, 11, 15
