How to create an empty array in NumPy

You can create an empty array in NumPy with the following code. If you want to learn Python then I will highly recommend you to read This Book.

Empty Array (Meaning 1)

import numpy as np
a = np.array([])
print(a)
print(type(a))
print(a.ndim)

Output:
[]
<class 'numpy.ndarray'>
1

Empty Array (Meaning 2)

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

Output:
[[ 0.00000000e+000  0.00000000e+000  0.00000000e+000]
 [ 0.00000000e+000  0.00000000e+000  6.85763116e-321]
 [ 7.25083853e+173 -1.06828331e-149  5.72918743e+250]]

Array with Zeros

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

Output:
[[0. 0. 0.]
 [0. 0. 0.]
 [0. 0. 0.]]
