|
```python
|
||
|
|
class numpy.ndenumerate(arr)
|
||
|
|
```
|
||
|
|
|
||
|
|
> Multidimensional index iterator.
|
||
|
|

||
|
|
|
||
|
|
```python
|
||
|
|
import numpy as np
|
||
|
|
|
||
|
|
a = np.arange(0, 12).reshape((4, 3))
|
||
|
|
print(a)
|
||
|
|
print()
|
||
|
|
|

|
|
for index, x in np.ndenumerate(a):
|
||
|
|
print(index, x)
