I'm glad that Eryksun was able to help, now would somebody like to 
explain what was going on?

I don't even understand the answer given. I tried entering "Kernel => 
Restart" at the iPython prompt, and got a SyntaxError.

In [1]: Kernel => Restart
------------------------------------------------------------
   File "<ipython console>", line 1
     Kernel => Restart
             ^
SyntaxError: invalid syntax
