stop server socket python code example

Example 1: close connection socket python

### Answer to: "close connection socket python" ###

sock.close();
sock.shutdown(socket.SHUT_RDWR);

###
#	sock.close():
#	Decrements the handle count by one and if the handle count has reached zero
#	then the socket and associated connection goes through the normal close
#	procedure (effectively sending a FIN / EOF to the peer) and the socket is
#	deallocated.
#	
#	Docs: https://docs.python.org/3/library/socket.html#socket.close
#	Close a socket file descriptor. This is like os.close(), but for sockets.
#	On some platforms (most noticeable Windows) os.close() does not work for
#	socket file descriptors.
#	
#	
#	sock.shutdown(socket.SHUT_RDWR):
#	For reading and writing closes the underlying connection and sends a FIN /
#	EOF to the peer regardless of how many processes have handles to the socket.
#	However, it does not deallocate the socket and you still need to call close
#	afterward.
#	
#	
#	Docs: https://docs.python.org/3/library/socket.html#socket.socket.shutdown
#	Shut down one or both halves of the connection. If how is SHUT_RD, further
#	receives are disallowed. If how is SHUT_WR, further sends are disallowed.
#	If how is SHUT_RDWR, further sends and receives are disallowed.

Example 2: python socket disconnect

import select
import socket

ip = '127.0.0.1'
port = 80

conn = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
conn.connect((ip, port))

while True:
    try:
        ready_to_read, ready_to_write, in_error = \
            select.select([conn,], [conn,], [], 5)
    except select.error:
        conn.shutdown(2)    # 0 = done receiving, 1 = done sending, 2 = both
        conn.close()
        # connection error event here, maybe reconnect
        print('connection error')
        break
    if len(ready_to_read) > 0:
        recv = conn.recv(2048)
        # do stuff with received data
        print(f'received: {recv}')
    if len(ready_to_write) > 0:
        # connection established, send some stuff
        conn.send('some stuff')
