python 简单UDP套接字编程反馈错误

iolop

UDPClient.py

#!/usr/bin/env python   
#import socket moudle
from socket import *
serverName = '183.220.109.66'
serverPort = 12000
clientSocket = socket(AF_INET,SOCK_DGRAM)
message = raw_input( 'Input lowervase sentence:' )
clientSocket.sendto(message,(serverName,serverPort))
modifiedMessage,serverAddress = clientSocket.recvfrom(204
print modifiedMessage
clientSocket.close()



UDPServer.py

#!/usr/bin/env python
#import socket moudle
from socket import *
serverPort = 12000
clientSocket = socket(AF_INET,SOCK_DGRAM)
serverSocket.bind(('',serverPort))
print "The server is ready to receive"
while True:
        message,clientAddress=serverSocket.recfrom(204
        modifiedMessage = message.upper()
        serverSocket.sendto(modifiedMessage,clientAddress)

-----UDPServer.py在终端执行反馈消息
# ./udpserver.py
Traceback (most recent call last):
  File "./udpserver.py", line 6, in <module>
    serverSocket.bind(('',serverPort))
NameError: name 'serverSocket' is not defined


请问这是为什么呢？

同样的问题，在建立TCPServer也是相同的情况
TCPServer.py

#!/usr/bin/env python
#import socker moudle
from socket import *
serverPort=12000
clientSocket=scoket(AF_INET,SOCK_STREAM)
serverSocket.bind(('',serverPort))
serverSocket.listen(1)
print 'The server is ready to servive'
while 1:
        connectionSocket, addr=serverSocket.accpet()
        sentence =connectionSocket.recv(1024)
        capitalizedSentence=sentence.upper()
        connectionSocket.send(capitalizedSentence)
        connectionSocket.close()

终端反馈
# ./tcpserver.py
Traceback (most recent call last):
  File "./tcpserver.py", line 5, in <module>
    clientSocket=scoket(AF_INET,SOCK_STREAM)
NameError: name 'scoket' is not defined
