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 [].

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] Indexing a bytearray results in unsigned bytes.
>>> pt[0] 50 >>> pt[5] 90 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.
I was looking for an answer to 'How may you convert binary into decimal values?' and found this question, so I want to complete Malik Brahimi's answer as much as I can.
Basically, what you can do is to create a list of ones and then iterate through them in order to create decimal list:
b_list = ['0', '1', '10', '11', '100', '101'] # Note, that values of list are strings res = [int(n, 2) for n in b_list] # Convert from base two to base ten print(res) # Output: # User@DESKTOP-CVQ282P MINGW64 ~/desktop # $ python backpool.py # [0, 1, 2, 3, 4, 5] You may note, that we can use this way to convert values with different bases: binary, hex and so on.
