You can print it by:

print(b'Caption FreeSpace ... \r\r\n\r\r\n'.decode())

Result:

Caption FreeSpace ...

my_str = "hello world"

Converting string to bytes

my_str_as_bytes = str.encode(my_str)

Converting bytes to string

my_decoded_str = my_str_as_bytes.decode()

You can remove the characters with translate like so 

b'Caption FreeSpace ... \r\r\n\r\r\n'.translate(None, b'\r\n')

which results in 

b'Caption FreeSpace Size C: 807194624 63869808640 D: Y: 216847310848 2748779065344 '

If you know the encoding of the returned data you may want to use decode which will give you a string for further processing.
For example, assumed it is encoded in utf-8, you can just call decode with its default value and directly call split on it to split by white-space characters to get an array like this 

b'Caption FreeSpace ... \r\r\n\r\r\n'.translate(None, b'\r\n').decode().split()

Result 

['Caption', 'FreeSpace', 'Size', 'C:', '807194624', '63869808640', 'D:', 'Y:', '216847310848', '2748779065344']
