title: Tkinter Treeview values in loop Python
body: <p>I have a list of integers and I want to add this ints as values in treeview in Tkinter. Something like that:</p>
  
  <p>Code:</p>
  
  <pre><code>  list_of_ints = [1,2,3,4]
  
    for i in list_of_ints:
      self.tree.insert("" ,0, text="", values=(i,"No. of obj.","Accuracy","Coverage"))
  </code></pre>
  
  <p>Output:</p>
  
  <pre><code>1 2 3 4 No. of obj. Accuracy Coverage
  </code></pre>
  
  <p>Output is columns of treeview. But I really don't know how refer to this values. Moreover I don't know how much values in the array.</p>
