hi, i made a program in python but received global name error. the program
code;
serverhost = '127.0.0.1'
serverport = 2000
BUFSIZ = 1024
addr = (serverhost,serverport)
if str(sys.argv).find("-s") == -1:
cs = socket(AF_INET, SOCK_STREAM,0) # create a TCP socket
cs.connect(addr)
key=1
main()
else:
serversock = socket(AF_INET, SOCK_STREAM) # create a TCP socket
serversock.bind(addr)
serversock.listen(2)
key=2
print 'waiting for connection…'
while 1:
clientsock, addr = serversock.accept()
print '…connected from:', addr,clientsock
main()
serversock.close()
what is difference cs and clientsock? i use cs in main() function or others,
but don't use clientsock not call from main() " data = clientsock.recv(BUFSIZ)
NameError: global name 'clientsock' is not defined "
i am sorry, i little know english
