How to convert bytes to string to integers? python

Question

I want to get an int list representing bytes in a string.

Answer 1

One option for Python 2.6 and later is to use bytearray:

>>> b = bytearray('hello')
>>> b[0]
104
>>> b[1]
101
>>> list(b)
[104, 101, 108, 108, 111]

For Python 3.x, you need bytesan object, not a string anyway, and therefore can just do it

>>> b = b'hello'
>>> list(b)
[104, 101, 108, 108, 111]

Answer 2

Do you mean ascii values?

nums = [ord(c) for c in mystring]

or

nums = []
for chr in mystring:
    nums.append(ord(chr))

Answer 3
