My input accepts the input for two+ arguments, but doesn't accept when I need only a single argument; my code is suppose to be a "command line prompt" that is suppose to accept input from the user to create router interfaces and connections. I use argNum = len(delimitedInput), which is my input, and have the code follow based on the if statements. However, the if argNum == 1 is not working, while the other are working perfectly. Any help here is appreciated and here's my code below:
while 1:
try:
message, address = clientSocket.recvfrom(8192) # Buffer size is 8192. Change as needed.
if message:
print (address, "> ", message.decode())
except:
pass
input = getLine();
if(input != False):
#output input
print("input is: ", input)
#split the input into delimitedInput
delimitedInput = input.split(' ')
#argNum is number of arguments the user typed
argNum = len(delimitedInput)
command = delimitedInput[0]
print("The number of arguments is ", argNum)
#TODO: Accepting one argument
if argNum == 1:
(command) = delimitedInput[0]
if command == "test":
print("test")
if command == "status":
print("The router is listening and accepting connections to the following ports: ")
print(mainlist)
print("The router's name is ", routername)
if command == "routerconnect":
print("The following routers are connected to this router with the cost: ")
print(connectionlist)
#Accepting two arguments
if argNum == 2:
port = delimitedInput[1]
(command, port) = delimitedInput
#listenport + acceptport built into one command with a space to setup the listening port
if command == "mainport":
incomingPort = int(port)
clientSocket.bind(('', incomingPort))
mainlist.append(incomingPort)
print("You are now listening and accepting connections to the this port:")
print(mainlist)
routername = "R" + str(incomingPort)
print("The router name is also now: ", routername)
#Accepting three arguments
if argNum == 3:
port = delimitedInput[1]
port2 = delimitedInput[2]
if command == "remote":
#port = remote host address
rmaddress.append(port)
#port2 = remote port
rmport.append(port2)
remoteAddressAndPort = (port, int(port2))
print("Command: ", command)
print("Remote host address: ", port)
print("Remote port: ", port2)
clientSocket.sendto(input.encode(), remoteAddressAndPort)
#Accepting four arguments
if argNum == 4:
port = delimitedInput[1]
port2 = delimitedInput[2]
message = delimitedInput[3]
(command, port, port2, message) = delimitedInput
#Sending a message to other UDP chat hosts using the remoteport command
if command == "send":
#port = remote host address; this HAS TO BE 127.0.0.1 FOR SOME REASON
rmaddress.append(port)
#port2 = remote port
rmport.append(port2)
remoteAddressAndPort = (port, int(port2))
print("Command: ", command)
print("Remote host address: ", port)
print("Remote port: ", port2)
print("Message: ", message)
clientSocket.sendto(input.encode(), remoteAddressAndPort)
#setting up router cost
if command == "cost":
#port = remote host address, which has to be 127.0.0.1
#port2 = remote port you want to connect to
#message = cost to move to that router
message = int(message)
port2 = ("R" + port2)
#Add to the connection/cost list
connectdiction.append(str(port2) + " " + str(message))
#Add to the "what is this connected to" list"
connectionlist.append(port2)
print("Command: ", command)
print("Remote host address, which has to be 127.0.0.1: ", port)
print("Remote port, which should be the just the number: ", port2)
print("Cost to connect to this router: ", message)
