How to create an empty, full NumPy array, array with all zeros,array with all ones

Sure, here is how you can create different types of arrays using NumPy in Python:

1. Empty Array:

import numpy as np
empty_array = np.empty((3,3))
print(empty_array)

This will create a 3x3 empty array. The numbers in the array are random because the array is initialized with whatever values were already at that memory location.

2. Full Array:

import numpy as np
full_array = np.full((3,3), 7)
print(full_array)

This will create a 3x3 array filled with the number 7.

3. Array with all zeros:

import numpy as np
zeros_array = np.zeros((3,3))
print(zeros_array)

This will create a 3x3 array filled with zeros.

4. Array with all ones:

import numpy as np
ones_array = np.ones((3,3))
print(ones_array)

This will create a 3x3 array filled with ones.
