Question

Consider the following code snippet.

import numpy

X = "1 2.4 3.9 4 5.7 6 7"

Y = [abs (float (i)) for i in x.split()]

Z = numpy.array([a for a in y])

p = numpy.split(z, 2)

print(p[1][0] + 4 ** 2)

What will be printed by executing the above code?

a) 21.0

b) Error

c) 81.0

d) 62.41

Answer 1

The Python code generates an Error due to mistyped variable names that are case-sensitive and an invalid use of the numpy.split function for an array of size 7.

Step-by-step explanation:

The question involves a code snippet in Python that uses the NumPy library to manipulate a string of numbers and perform calculations. The string 'X' is split into a list of its numerical components, converted to floats, and their absolute values are taken to form the list 'Y'.

This list is then converted into a NumPy array 'Z'.

The array is split into two parts, but a key error in the code is the split function is unable to equally divide an array of 7 elements into 2 parts.

However, ignoring this, the incorrect capitalization in the variable names would actually cause the code to throw an Error at runtime because of undefined variables, but if corrected, the first element of the second split part of the array, which is 5.7, would be accessed and added to 4 ** 2 (which equals 16), resulting in a sum of 21.7, but this choice is not given, indicating a necessary revision of the options or setup of the question.

The correct answer among the provided choices would be (b) Error due to the reasons mentioned above.

Answer 2

Step-by-step explanation:

Error!

By executing "numpy.split(z, 2)" u should know that the len of y is divisible by 2 or else it will return Error

Answers: B
