python 3.6 - How to print a function in tkinter -


i made script parses song title ice-cast stream, shows in python shell. have many questions how print text in tkinter gui, not function-text.

how can print in tkinter gui?

here code:

import vlc import os import requests import re  stream_url = 'http://oneradio.su:8000/trance' r = requests.get(stream_url, headers={'icy-metadata': '1'}, stream=true) icy_meta_int = r.headers.get('icy-metaint')  def gettitle():     chunk in r.iter_content(50):         l = str(chunk)         match = re.search(r"streamtitle='(.*)';", l)         while match none:             return none         title = match.group(1)         print(title)  gettitle() root = tk()  root.resizable(width=false, height=false) root.wm_title("radio") root.iconbitmap(default='logo.ico')  p = vlc.mediaplayer("http://oneradio.su:8000/trance")  def play():     p.play()     play.configure(state=disabled)  def stop():     p.stop()     play.configure(state=normal)  def hv():     p.audio_set_volume(100)  def lv():     p.audio_set_volume(50)  logoimg = photoimage(file="logo.png") logo = label(root, image=logoimg) logo.photo = logoimg logo.place(relx=.3, rely=.0)  st = label(root, text="now playing:") st.place(relx=.3, rely=.3)  play = button(text="play", command=play) play.place(relx=.0, rely=.6)  stop = button(text="stop", command=stop) stop.place(relx=.8, rely=.6)  hv = button(text="100%", command=hv) hv.place(relx=.6, rely=.6)  lv = button(text="50%", command=lv) lv.place(relx=.2, rely=.6) root.mainloop()

you can use tkinter stringvar type , update go, mainloop automatically update label text in stringvar. use get() function data stringvar object, , set(str) set text in stringvar object. use config on label.

import tkinter tk  window = tk.tk()  def number_range(x):     = 1     while < x:         yield         += 1  generator = number_range(500)  stringvar = tk.stringvar() stringvar.set("some placeholder")  example_label_one = tk.label(window, textvariable=stringvar) example_label_two = tk.label(window, text="some placeholder") example_label_one.pack() example_label_two.pack()  def update_labels():     string = "updated %s times" % generator.next()     window.after(500, lambda: stringvar.set(string))     window.after(500, lambda: example_label_two.config(text=string))     window.after(1000, update_labels)  # after function inserts command mainloop window.after(500, update_labels) window.mainloop()
