照搬书上的UDP socket

迷糊

1）UDPClient.py

from socket import *
severName = 'hostname'
severPort = 12000
clientSocket = socket(AF_INET, SOCK_DGRAM)
message = input('Input lowercase sentence:')
clientSocket.sendto(message, (severName, severPort))
modifiedMessage, serverAddress = clientSocket.recvfrom(2048)
print(modifiedMessage)
clientSocket.close()

2）UDPServer.py

from socket import *
severName = 'hostname'
severPort = 12000
clientSocket = socket(AF_INET, SOCK_DGRAM)
message = input('Input lowercase sentence:')
clientSocket.sendto(message, (severName, severPort))
modifiedMessage, serverAddress = clientSocket.recvfrom(2048)
print(modifiedMessage)
clientSocket.close()

发现书上说要两台机子，测试gg
