Memoryview for List

[perfringo]

Good practice is to make sure you understand what memoryview is. Best place to start is Python official documentation (class memoryview(obj))

Create a memoryview that references obj. obj must support the buffer protocol. Built-in objects that support the buffer protocol include bytes and bytearray.

So we need bytes or bytarray (or have our own class).

Maybe following will give general idea:

>>> m = memoryview(b'[1, 2, 3]')
>>> list(m)
[91, 49, 44, 32, 50, 44, 32, 51, 93]
>>> for el in m:
...     print(chr(el))
...
[
1
,
 
2
,
 
3
]
>>> type(m)
