NumPy - Creating Arrays

What will be the output of this code?

import numpy as np
arr = np.ones(4, dtype=bool)
print(arr)

A[False False False False]

B[1 1 1 1]

C[True True True True]

D[0 0 0 0]

Step-by-Step Solution

Solution:

Step 1: Understand dtype=bool in np.ones()
np.ones() creates an array of ones, and with dtype=bool, ones convert to True.
Step 2: Check the printed output
The array will have 4 elements, all True boolean values.
Final Answer:
[True True True True] -> Option C
Quick Check:
np.ones() with bool dtype = True values [OK]

Quick Trick: Ones become True when dtype=bool is used [OK]
