title: Wm attributes and '-zoomed' doesn't work?
body: <p>I tried the same codes in Python2 and Python3 to see if the wm attributes would work in Python3 (I generally use Python2)</p>
  
  <pre><code>root.call("wm", "attributes", ".", "-zoomed", "True")
  root.attributes('-zoomed', True)
  root.wm_attributes('-zoomed', True)
  </code></pre>
  
  <p>but it gives me this error:</p>
  
  <pre><code>_tkinter.TclError: wrong # args: should be "wm attributes window ?-alpha ?double?? ?-transparentcolor ?color?? ?-disabled ?bool?? ?-fullscreen ?bool?? ?-toolwindow ?bool?? ?-topmost ?bool??"
  </code></pre>
  
  <p>I also tried these:</p>
  
  <pre><code>root.wm_state('-zoomed', True)
  root.state('-zoomed', True)
  </code></pre>
  
  <p>but gave me this error:</p>
  
  <pre><code>TypeError: wm_state() takes at most 2 arguments (3 given)
  </code></pre>
  
  <p>I'm using Windows 7 although it seems to work for @ParvizKarimli who is also using windows 7.</p>
  
  <p>Am I doing it wrong ? And is there an alternate method to maximize the window ?</p>
