Python 3.5 bytes to float conversion help

Hi

Some time ago i've made a program in Python to read memory and output to an arduino to get a speedometer. Now in the meantime of drumming, coding, keep trying to get the values from Initial D Special Stage and missing my ex-girlfriend, I want to do the same but with another game and using other methods.

The game that i'm working is Race Driver GRID. I've made a simple UDP listener in Python, but I never worked with bytes (the memory reading module was a pain for me), so IDK what I have to do with this telemetry send by the game:

b'6t}@q\x1f\x19>\xe4\x08\xc5E\x00\x08%\xbb\xc5\xaa\x84C&\xfe\x05A\xb3\x14\x89\xc4@\x88\xa4;^\xc2\x9b\xb9\x95;\xa4\xbb\x9f\xe5u\xb8t#H>\x823\xee\xb8\x15\x10{\xbf\x00\x9bz\xbf\xed\x05w=\xf3\xc7G\xbe\xe9<\x85\xc0\x1b\xda\x82\xc0 \x9d\x81\xc0\x9e\x9f~\xc0\xc2\xbc\xf8>\x8c\x9dU\xbf\x9d\xc6\xe6?\xe6/P?\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x80?\x00\x00\x80?`\x9380\xc0\\\xe4/\x00\x00\x00\x00'

I know that it's a byte object, so i've started researching from there, but without results. Reading in a post from the arduino forums, combining the 28, 29, 30 and 31 byte i'll get the speed, but my problem is how to do that. I want to know how to get those bytes and combining them. With that not only I can measure the speed, also i can get other kind of data (gear, rpm, etc....) and send it to an arduino (i donde it before)

something like

import socket

UDP_IP ="0.0.0.0"
UDP_PORT =20777

sock = socket.socket(socket.AF_INET,# Internet
socket.SOCK_DGRAM)# UDP
sock.bind((UDP_IP, UDP_PORT))
import struct
x =0
y =4
data, addr = sock.recvfrom(1024)
output =struct.unpack('f', data[x:y])# 4 bytes at a time

Well, yesterday (THE IRONY!) i've figured out hot to get the data

while True:
data, addr = sock.recvfrom(1024) # Buffer Size
speed = struct.unpack("27xf116x", data)
gear = struct.unpack("131xf12x", data)
print([int(speed[0]*3.6), int(gear[0])])

The sad part is couldn't get the RPM. IDK if this the right way to get the data but at least it worked

Well, i've tested your example and it worked too. So, IDK what choose
