Python problem with sending/receiving packets to local host address using socket and dpkt module

Question

I'm trying to send an ICMP echo packet to my local host address and then return a response acknowledging that the packet was received. So far I have

def send_echo(socket, data, id, seq, dest):
    echo = dpkt.icmp.ICMP.Echo()
    echo.id = id
    echo.seq = seq
    echo.payload = bytes(data, 'utf-8')

   icmp = dpkt.icmp.ICMP()
   icmp.type = dpkt.icmp.ICMP_ECHO
   icmp.data = echo

   icmp_packed = icmp.pack()
   socket.sendto(icmp_packed, destination) #sending packet here 

And then I wrote a function to receive this packet as follows:

def recv_response():
    mySocket = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_ICMP) 
    while True:
    try:
        received, addr = mySocket.recvfrom(1024)
        break
    except socket.error:
        test = 0
    return received

The loop gets stuck, so my guess is its not sending correctly but I'm not certain.

Main function:

def main():
    host_port = tuple(["127.0.0.1", 65432])
    send_echo(make_socket(50,50), "data", 0, 0, host_port)    
    recv_response()

So I get stuck in the loop in response but I'm not really sure if this is a sending problem or a receiving problem. Any help would be really appreciated.

Edit: Thanks Barmar, I used wireshark and successfully sent to 8.8.8.8. So the issue is with the receiving function.
