python - Connection status function gives error and does not working right -

this part of python software control smart tv. have function "connection_status".

import fcntl, socket, struct import base64 import time, datetime import netifaces tkinter import *  root = tk() root.title("pepin's samsung smart tv remote") root.geometry("391x595") #391  class application():     """pepin's samsung smart tv remote"""      def __init__(self, master):          self.master = master         self.create_widgets()      def connection(self):          self.connection_status()       def connection_status(self): // function not work right.          try:              connection_status = sock.recv(64)             print("status: connected")             self.label_connection_status['text'] = 'status: connected'          except socket.timeout:              connection_status = ""             print("status: disconnected")             self.label_connection_status['text'] = 'status: disconnected'          self.master.after(1000, self.connection_status, self.master)      def create_widgets(self):             btn_connect = button(self.master, text = "connect tv", width=19, height=2, command = lambda: self.connection())   app = application(root) root.mainloop() 

but when call function, outputs me error:

status: connected exception in tkinter callback traceback (most recent call last):   file "/usr/lib/python2.7/lib-tk/tkinter.py", line 1535, in __call__     return self.func(*args)   file "/usr/lib/python2.7/lib-tk/tkinter.py", line 586, in callit     func(*args) typeerror: connection_status() takes 1 argument (2 given) 

and if tv disconnects, status stay "connected"!

you calling self.connection_status line of code:

self.master.after(1000, self.connection_status, self.master) 

that result in following function call:

self.connection_status(self.master) 

however, connection_status doesn't accept arguments other self automatically added python. why getting error connection_status() takes 1 argument (2 given). self first argument, , self.master second argument, function designed accept self.

there never reason pass object attribute method of same object, since method has immediate access attributes. so, simple solution remove parameter after call:

self.master.after(1000, self.connection_status)
