How do I convert my byte data to integer using python?

Question

I have a byte data is like: b'\xc4\x03\x00\x00\xe2\xecqv\x01'.
How do I convert this to integer like index by index.

It depends on how you want to interpret that as integers. You can take each byte and convert it to integer, or each bit, or each 16-bit word or interpret the whole data as one integer, or anything else. In the end it sums up to question: how did you get that binary data in the first place? — zvone

a bytes object is basically already a (immutable) sequence of integers.

b = b'\xc4\x03\x00\x00\xe2\xecqv\x01'
b[0] # 196
lst = list(b)
#  [196, 3, 0, 0, 226, 236, 113, 118, 1]

Just access throug indexes:

>>> b = b'\xc4\x03\x00\x00\xe2\xecqv\x01'
>>> b[0]
196

>>> for i in b:
...     print(i)
... 
196
3
0
0
226
236
113
118
1

If you have Python v.3, you can use the int_from_bytes() function:

int.from_bytes(b'\xc4\x03\x00\x00\xe2\xecqv\x01', byteorder='big')
