This question tests your understanding of Singed and Unsinged Integers In Python.

What would be the output of the following code snippet?

import array as arr
numbers_list = [5,6,8]

nums_1 = arr.array('f', [])
nums_2 = arr.array('I', numbers_list)

numbers_list.append(-9)
nums_3 = arr.array('i', numbers_list)

print(len(nums_3))

Answer: B

Explanation:

• nums_1 is an empty array of floats.
• nums_2 is an array of unsigned integers containing 5, 6, and 8.
• numbers_list is modified to include -9.
• nums_3 is an array of signed integers containing 5, 6, 8, and -9.
• The length of nums_3 is 4.

So, the final output of the code will be:
