What is the output of the following snippet? tup = (1, 2, 4, 8) tup = tup[-2:-1] tup = tup[-1] print(tup)

tup = (1, 2, 4, 8)
tup = tup[-2:-1]
tup = tup[-1]
print(tup)

• 44
• (4,)
• 4
• (4)

Explanation: Let’s analyze the code line by line:

• Line 1: the four-element tup tuple is created
• Line 2: tuples can be sliced, so the following slice result is assigned to tup: (4,)
• Line 3: since the tup tuple is a one-element tuple now (4,), indexing the last and only element will “extract” it from the tuple, and assign to the tup variable as an integer value.
• the value 4 will then be printed to the screen.
