I make code for displaying two serial read string in two different label using tkinter GUI.. My code is running and window also popped up but values are not displaying.. Help me to solve this issue.. Here is my code

import serial
import tkinter 
from tkinter import *
import time
class SerialViewer(Tk):
 def _init_(self):
      self.win = Tk()
      self.ser=serial.Serial('/dev/ttyS0',9600)
 def makewindow (self):
      frame1 =Frame(self.win)
      frame1.pack()
      self.v=StringVar()
      self.v.set=('default')
      label=Label(frame1,textvariable=self.v,relief=RAISED)
      label.pack(side=LEFT)
      frame2 = Frame(self.win)
      frame2.pack()
      self.d=StringVar()

       print(self.ser.write("*01T%"))
       data=self.ser.readline(self.ser.inWaiting())
       self.v.set(data)
       time.sleep(2)
       print(self.ser.write('*00T%'))
       data1=self.ser.readline(self.ser.inWaiting())
       self.d.set(data1)
       self.win.after(100,self.update)
 def run (self):
       self.makewindow()
       self.update()
       self.win.mainloop()
app=SerialViewer()
app.mainloop()

As said in comment that the method _init_ needs to be changed to __init__ and the recursion error is coming because the __init__ method of parent class wasn't called. Please add that call like below:

class SerialViewer(Tk):
    def _init_(self):
        super(SerialViewer, self).__init__() # Call the initializer method of parent class
        self.win = Tk()
        self.ser=serial.Serial('/dev/ttyS0',9600)

Hope this helps!!
