How to make a regexp matching for a row of bytes?
For example how to check with regexp that binary data consists of (0-10 byte) characters?

data = 0x00 0x05 0x02 0x00 0x03 … (not a string, binary data)

Answer 1

If you want to check that the string contains only characters between chr(0) and chr(10), simply use

re.match('^[\0-\x0A]*$',data)

For Python3, you can do the same with byte strings:

re.match(b'^[\0-\x0A]*$',b'\x01\x02\x03\x04')
