Start communication with UDP and send and receive with TCP

I wrote it as a trial, but I didn't seem to use it, so a memo for some time

UDPServer_and_TCPClient.py

#Run UDP server and TCP client
from socket import socket, AF_INET, SOCK_DGRAM, SOCK_STREAM

#A function that starts a connection with TCP and sends data
def tcp_send():
	with socket(AF_INET, SOCK_STREAM) as s:
		s.connect(('127.0.0.1', 50010))
		while True:
			s.sendall(b'hello')

#UDP server
udp_server = socket(AF_INET, SOCK_DGRAM)
udp_server.bind(('', 8888))

while True:
	msg, address = udp_server.recvfrom(8192)
	if msg.decode('utf-8') == "tcp_start":
		#When you receive a specific string, connect the TCP client and send
		tcp_send()
		break

udp_server.close()

TCPServer_and_UDPClient.py

#Run TCP server and UDP client
from socket import socket, AF_INET, SOCK_DGRAM, SOCK_STREAM

#Function to send UDP
def udp_send(): 
	udp_client = socket(AF_INET, SOCK_DGRAM)
	udp_client.sendto("tcp_start".encode(), ("127.0.0.1", 8888))

#Create TCP server
with socket(AF_INET, SOCK_STREAM) as tcp_server:
	tcp_server.bind(('127.0.0.1', 50010))
	tcp_server.listen(1)
	
	#UDP transmission
	udp_send()
	while True:
		conn, addr = tcp_server.accept()
		with conn:
			while True:
				data = conn.recv(1024)
				print(data.decode('utf-8'))
