It's a sequence of bytes and you've asked Python to print its
string representation. So where the bytes are unprintable
ascii codes it shows you the hex, thus:
Those are all single bytes in hex
that byte has the ascii value for the letter 'h'
(ie. its 104 in decimal)
More bytes as hex
The three ascii characters '7','p','^'
(or 55,112,94 in decimal)
More hex bytes
more bytes as hex... you get the idea?
However that doesn't mean that those are really what the
data represents. The first 4 bytes could be a 32 bit integer,
or a short floating point value.
Similary the 7p^ sequence could be three bytes from within an
You really need to know whats being thrown at you down the socket
otherwise you have very little hope of accurately decoding it.
And to decode it you need to use the struct module.
