Make a memory representation of using bytearray int int in Python 2.7

b = bytearray(1)
m = memoryview(b)

Since type (b [0]) is int, I would expect type (m [0]) to also be int. Starting with Python 3.2, this is true. But in Python 2.7, the type is str. I need to be able to pass a memoryview for functions that expect an int array.

In Python 2.7, I can create a wrapper class and override it __getitem__. But is there a trick to tell the memoryview object to return int elements?

No, there is no way to call memoryview __getitem__to return objects int.

Use ordshould do the trick:

Python 2.7.5+ (default, Sep 19 2013, 13:48:49) 
>>> b = bytearray(1)
>>> m = memoryview(b)
>>> m[0]
'\x00'
>>> ord(m[0])
0
>>> map(ord, m)
[0]
>>>

, Python 2 . Python 3 (unicode).
