I want to take an integer, that will be between 0 and 255, convert that to a hex string eg. '\xff' and then cast that to bytes to end up with b'\xff'. I had assumed that the following would work.

data_num = 255
data = chr(data_num)
data_byte = data.encode()

Any help would be appreciated

Did you consider using the built-in hex function?

data = hex(255)
data = data.encode()
print(data, type(data))

Output:

b'0xff' <class 'bytes'>
