GitHub上的socket小程序，很有意思。两个程序一个在cmd运行，一个在编译器运行
# Note :- Client and Server Must be connected to same Network# import socketmodules
import socket
# create TCP/IP socket
s = socket.socket()
# take user input ip of server
server = input("Enter Server IP: ")
# bind the socket to the port 12345, and connect
s.connect((server, 12345))
# receive message from server connection successfully established
data = s.recv(1024).decode("utf-8")
print(server + ": " + data)
while True:
# send message to server
new_data = str(input("You: ")).encode("utf-8")
s.sendall(new_data)
# receive message from server
data = s.recv(1024).decode("utf-8")
print(server + ": " + data)
# close connection
s.close()

finally:
