Here is server code (server.py) and client code (client.py). The client wants to send the word hello to the server.

Server code:

import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('localhost', 10095)
sock.bind(server_address)
sock.listen(1)
while True:
  print('waiting for a connection')
  connection, client_address = sock.accept()
  print("received a new connection")

Client code: 

import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('localhost', 10095)
sock.connect(server_address)
sock.send("hello".encode())

The server code runs and then the client code. The server did not receive the hello message,
but the client claims that it did send it. What is the reason?

# Answer: The server did not use the recv method to read
