python convert bytearray to numbers in list

Question

For the following python codes:

pt  = bytearray.fromhex('32 43 f6 a8 88 5a 30 8d 31 31 98 a2 e0 37 07 34')
state = bytearray(pt)

If I use:

print state

It gives out 2Cö¨ˆZ0?11˜¢à74

Then how to recover the content in the bytearray? For example, to put them in a list like [].

Answer 1

You can convert between a bytearray and list using the python built in functions of the same name.

>>> x=[0,1,2,3,4]      # create a list 
>>> print x
[0, 1, 2, 3, 4]
>>> y = bytearray(x)   # convert the list to a bytearray    
>>> print y
(garbled binary)               <-- prints UGLY!
>>> z = list(y)        # convert the bytearray back into a list
>>> print z
[0, 1, 2, 3, 4]        

Answer 2

Indexing a bytearray results in unsigned bytes.

>>> pt[0]
50
>>> pt[5]
90

Answer 3

You can make your own method with simple string methods:

string = '32 43 f6 a8 88 5a 30 8d 31 31 98 a2 e0 37 07 34'
number = [int(i, 16) for i in string.split()]

Now you have a list of the converted numbers as you wanted.
