title: tkinter error "unable to detect undefined names"
body: <p>I need to use tkinter but I got that messages when I write <code>from tkinter import *</code> I've tried <code>import tkinter as tk</code> for example it works but have to put tk. before every thing , so why <code>from tkinter import *</code> does not work ? Python cannot actually read any of its commands it gives me 'NameOfCommand' may be undefined from star impors 
  Is that normal? cause a lot of warning messages pop up and python gives me no automatic complete of a sentence as usual and as I study in the tutorials </p>
  
  <pre><code>from math import *
  x=ceil(5.6)
  print(x) # prints 6 
  </code></pre>
  
  <p>I've recently installed python 3.6 , even though math gives me the same warning says ' 'Ceil' may be undefined or defined from star imports:math  ' </p>
