I have a basic program where in a Tkinter window a user presses a button that generates a string in a listbox. Using a second send button, I want to transfer those strings through a socket server to a second client. The message printed to the console at the point of departure (client1) is a tuple, and it can be iterated through with a for loop to make it more legible i.e. each element is printed to a new line. Using a print function at the point of arrival (client2), the same tuple is produced, but trying to use a for loop on it iterates through each character in the group of strings, as opposed to each element of the tuple as desired.
This is client1:

tkinter.mainloop()
As I said above, the msg variable in client2, the one that receives the message, is printed as a tuple but a for loop will iterate over each character of the strings contained.
Using the pickle module I received two separate errors.
When I pass .decode("utf-8) and then .loads() it says "Could not find MARK).
Without the .decode(), the error is "unpickling stack underflow".
My desired outcome is for each of the individual strings that arrive over the TCP socket to be added to the listbox in client2 on a new line, and without the ('', '') symbols.
Should I try to convert it to a .json object?
Or will another networking module produce better results?
I'm sorry about the length of code and the potentially obvious answer. Beginner to networking.

I am making a python chatroom application for school with a functioning clientside and serverside script. I am now adding multiple functionalities to the chatroom to make it easier to use, one of which is hopefully spam protection.

A way to do this is using the widget.unbind(sequence, funcid = None) method.
This, as the name suggests, deletes the bindings on w for a determined event.
Then you can use the tkinter built-in method root.after() to call a function that you create to rebind the button to the function.
But for this to work you need to bind the send_button using the .bind() method.
def rebind():
send_button.bind("<Button-1>", send)
send_button.bind("<Button-1>", send)
send_button.unbind("<Button-1>", funcid=None)
top.after(time in miliseconds, rebind)

I am sending wrong ip?

I am trying to make a simple chat application using Python 3. I have seen this work in the past, where my client is able to connect to my server, and messages can be sent successfully. I want to move the app from a script working in the python idle shell to a GUI built with TKinter. Using entry and button widgets, a client can connect to the server for a fraction of a second, then is immediately disconnected. This only seems to happen because I am trying to use tkinter.
Error message is:
%$%$ has connected.

All answers appreciated.
I am trying to create a simple "chat room" of the sort, where I do not know how many messages I will get from a client but my server will receive them all, display them and eventually respond. The problem is that when I click on the respond textbox, my code crashed. I am really unsure about where my problem lies and any help will work.

have a good time :-)
Was trying to make a chat application written in Python, but for some reasons I don't know, when the 1st client sends data, it works but the 2nd or other client can't receive it until the other client tries to send a message and it works fine...
Here's my code for the client:
from Tkinter import *
from PIL import ImageTk, Image
from socket import *
from threading import Thread, Lock
import time
'#Connect to Server'
shutdown = False
host = "127.0.0.1"
port = 0
server = ("127.0.0.1", 12345)
s = socket(AF_INET, SOCK_DGRAM)
s.bind((host, port))
s.setblocking(0)
global alias
def sendmsg():
msg = alias + " : " + chatEntry.get("0.0", END).strip() + "\n"
#chatLog.config(state=NORMAL)
#chatLog.insert(END, msg)
chatEntry.delete(1.0, END)
#chatLog.config(state=DISABLED)
s.sendto(msg, server)
def recvmsg(name, sock):
while not shutdown:
try:
while True:
data = sock.recv(1024)
chatLog.config(state=NORMAL)
chatLog.insert(END, str(data))
chatLog.config(state=DISABLED)
print str(data)
except:
pass
alias = raw_input("Alias ==> ")
root = Tk()
'#Create a window'
frame = Frame(root, width=600, height=450, bg="black")
frame.pack()
'#Create a chat log'
chatLog = Text(root, font=("Determination Sans", 12))
chatLog.insert(END, "Connecting..... \n")
chatLog.config(state=DISABLED)
chatLog.place(x=13, y=13, width=425, height=329)
'#Create list of friends online'
friendsList = Text(root)
friendsList.config(state=DISABLED)
friendsList.place(x=445, y=13, width=142, height=329)
'#Create an entry where you can enter your message'
chatEntry = Text(root)
chatEntry.place(x=13, y=349, width=425, height=96)
'#Create a send button'
btnLogin = Button(root, text="SEND", command=sendmsg)
btnLogin.place(x=445, y=349, width=142, height=96)
'#Set it fixed, not resizable......'
root.resizable(width=FALSE, height=FALSE)
root.wm_title("Chat - Underchat")
Thread(target=recvmsg, args=("RecvThread", s)).start()
root.mainloop()
And here's my code for the server:
from socket import *
import time
'#Put IP here...'
'#Put Socket here...'
host = "127.0.0.1"
port = 12345
clients = []
s = socket(AF_INET, SOCK_DGRAM)
s.bind((host, port))
'#Set Blocking to 0 so it will accept basically everything'
s.setblocking(0)
quitting = False
print "server started....."
while not quitting:
try:
'#Receive 1024 bytes of data... Its basically 1KB :P '
data, addr = s.recvfrom(1024)
if "Quit" in str(data):
'#Quit if a specified string was detected...'
quitting = True
if addr not in clients:
'#If a new client was found, add them to the clients list'
clients.append(addr)
print time.ctime(time.time()) + str(addr) + ": :" + str(data)
for client in clients:
'#Send the data to all clients... This is a groupchat afterall :3'
s.sendto(data, client)
except:
'#Try again if something goes wrong.....'
pass
'#Close the connection when out of the loop'
s.close()
So any ideas? Thanks
