What is the output of the following Python code?
x = [1, 2, 3]
y = x + [4, 5]
z = x.extend([4, 5])
print(x, y, z)
Answer: Option
Explanation:
x is a list with values [1, 2, 3].
y is the result of concatenating x with [4, 5].
z is the result of extending x with [4, 5], but it returns None.
The values of x, y, and z are printed.
Thus, the output is [1, 2, 3, 4, 5] [1, 2, 3, 4, 5] None.
