What is wrong with my basic function if elif statement?

Currently my script prints the same thing each time when it should be printing the corresponding string

def vin(value):
    if value == 0:
     print("vin0")
    elif value == 1:
     print("vin1")
    elif value == 2:
     print("vin2")

It always prints vin0 no matter what value is. To simplify my question I have substituted in print for another more complex function. Here is a sample of the full code:

def socket_handler(sock):
    data = sock.recv(1024)
    print("Received %d bytes from socket: %s" % (len(data), data))
    if(len(data) == 0):
        # Unmanage the socket if it has been closed
        print("Remote has closed the connection")
        midimonster.manage(None, sock)
        sock.close()

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((DEVICE_IP, DEVICE_PORT))
midimonster.manage(socket_handler, s)

def vpow(value):
    if value > 0.9:
        s.send(bytes("sendir,4:1,1,38000,1,69,341,170,21,21,21,21,21,21,21,64,21,21,21,21,21,21,21,21,21,64,21,64,21,64,21,21,21,64,21,64,21,64,21,64,21,64,21,21,21,64,21,64,21,21,21,21,21,64,21,21,21,21,21,64,21,21,21,21,21,64,21,64,21,21,21,64,21,1517,341,85,21,3655\r", "utf-8"))

def vin(value):
    if value == 0:
        s.send(bytes("sendir,4:1,1,38000,1,69,341,170,21,21,21,21,21,21,21,64,21,21,21,21,21,21,21,21,21,64,21,64,21,64,21,21,21,64,21,64,21,64,21,64,21,64,21,21,21,21,21,64,21,21,21,21,21,21,21,21,21,21,21,64,21,64,21,21,21,64,21,64,21,64,21,64,21,1517,341,85,21,3655\r", "utf-8"))
    elif value == 1:
        s.send(bytes("sendir,4:1,1,38000,1,69,341,170,21,21,21,21,21,21,21,64,21,21,21,21,21,21,21,21,21,64,21,64,21,64,21,21,21,64,21,64,21,64,21,64,21,21,21,21,21,64,21,21,21,64,21,21,21,64,21,21,21,64,21,64,21,21,21,64,21,21,21,64,21,21,21,64,21,1517,341,85,21,3655\r", "utf-8"))
    elif value == 2:
        s.send(bytes("sendir,4:1,1,38000,1,69,341,170,21,21,21,21,21,21,21,64,21,21,21,21,21,21,21,21,21,64,21,64,21,64,21,21,21,64,21,64,21,64,21,64,21,64,21,64,21,64,21,21,21,21,21,21,21,64,21,21,21,21,21,21,21,21,21,64,21,64,21,64,21,21,21,64,21,1517,341,85,21,3655\r", "utf-8"))

What does my syntax need to be for the if elif at the bottom. Bear in mind what's coming in is vin0, vin1, vin2 up to vin15 and I need it to send the corresponding bytes
