Question
Choose the correct answer What will be the output after the following statements?
a = [0, 1, 2, 3] del a[:] print(a) Options SyntaxError [ ] [0, 1, 2, 3] NameError
Solution
The correct answer is [ ].
Here's why:
-
The first line
a = [0, 1, 2, 3]creates a listawith elements 0, 1, 2, 3. -
The second line
del a[:]deletes all elements from the lista. The[:]is a slicing operation that includes all elements of the list. So,del a[:]means delete all elements froma. -
The third line
print(a)prints the current state of the lista, which is now empty because all elements have been deleted. Therefore, it prints [ ], which represents an empty list.
