after doing "from tkinter import *" why ttk is not defined?
<p>After doing <code>from tkinter import *</code> why is <code>ttk</code> not defined? What does <code>*</code> mean?</p>

<pre><code>&gt;&gt;&gt; from tkinter import *
&gt;&gt;&gt; root = Tk()
&gt;&gt;&gt; asd = ttk.Treeview(root)
Traceback (most recent call last):
  File &lt;"pyshell#4"&gt;, line 1, in &lt;module&gt;
    asd = ttk.Treeview(root)
NameError: name 'ttk' is not defined
</code></pre>

<p>If I do <code>from tkinter import ttk</code>, then there is no problem. On using <code>*</code>, <code>ttk</code> must have been fetched. Then why is there an error?</p>
