Question

Consider the following assignment for a List L: L = [10, 20, 30, 40, 50, 60] Which print statement option will display the content in the following way? 60, 10, 20, 30, 40, 50

A.

print(L[-1] + L[1:])

B.

print(L[-1] + L[1:len(L)−1])

C.

print(L[len(L)−1] + L[1:len(L)])

D.

print(L[-1], L[1:])

Correct option is D


The print statement print(L[-1], L[1:]) will display the content of the list in the following way: 60, 10, 20, 30, 40, 50. Here's why:
· L[-1] accesses the last element of the list, which is 60.
· L[1:] accesses all elements starting from the second element, i.e., 10, 20, 30, 40, 50.
· When combined in the print statement, it will display 60, 10, 20, 30, 40, 50.
Important Key Points:
1. Negative Indexing: L[-1] accesses the last element of the list, which is 60.
2. List Slicing: L[1:] is a slice that gets all elements from index 1 to the end of the list, which is [10, 20, 30, 40, 50].
3. Print Format: The , in the print statement ensures that the elements are printed with a space in between.
Knowledge Booster:
· Option (a): L[-1] + L[1:] would result in a TypeError because you cannot concatenate an integer (L[-1], which is 60) with a list (L[1:]). This would lead to a mismatch in types.
· Option (b): L[-1] + L[1:len(L)-1] would also attempt to concatenate an integer with a list, which would cause an error. It also does not produce the correct desired output format.
· Option (c): L[len(L)-1] + L[1:len(L)] would lead to a TypeError due to concatenating an integer with a list, similar to option (a). Also, this slicing wouldn't correctly rearrange the elements in the desired order.
