title: python console app - values displayed / update information without printing new lines
body: <p>I want to have some values displayed, and be able to change them; I need the information to be updated, without printing new lines. Something like this:</p>
  <pre><code># all variables are displayed on the screen
  
  var1 = 0 
  var2 = 0
  var3 = 0
  
  def m_menu():
      global var1, var2, var3
      
      choice = input(&quot;Enter 1/2/3: &quot;)
      if choice == 1:
          var1 += 1
      elif choice == 2:
          var2 += 1
      elif choice == 3:
          var3 += 1
  </code></pre>
  <p>Kind of, like mainloop() in tKinter...How can I do this ?</p>
