## Index vs Slices / Views
This procedure is called indexing:
```python
import numpy as np
a = np.arange(0, 10)
idx = np.arange(2,5)
b = a[idx]
print(idx) # -> [2 3 4]
print()
print(b) # -> [2 3 4]
print()
print(np.may_share_memory(a,b)) # -> False
```
While this is called slicing:
```python
import numpy as np
a = np.arange(0, 10)
b = a[2:5]
print(b) # -> [2 3 4]
print()
print(np.may_share_memory(a, b)) # -> True
```
As you can see lies the biggest different in the creation of a view when we use slicing. Indexing creates a new object instead.
