## NumPy: Array Object Exercise-132 with Solution

Write a NumPy program to split array into multiple sub-arrays along the 3rd axis.

Sample Solution:

Python Code:

``````import numpy as np
print("\nOriginal arrays:")
x = np.arange(16.0).reshape(2, 2, 4)
print(x)
new_array1 = np.dsplit(x, 2)
print("\nsplit array into multiple sub-arrays along the 3rd axis:")
print(new_array1)
```
```

Sample Output:

```Original arrays:
[[[ 0.  1.  2.  3.]
[ 4.  5.  6.  7.]]

[[ 8.  9. 10. 11.]
[12. 13. 14. 15.]]]

split array into multiple sub-arrays along the 3rd axis:
[array([[[ 0.,  1.],
[ 4.,  5.]],

[[ 8.,  9.],
[12., 13.]]]), array([[[ 2.,  3.],
[ 6.,  7.]],

[[10., 11.],
[14., 15.]]])]
```
