Hmmmmmmmmmmmmmm!  I'm relieved that the code works!

I've just encountered something strange.

I haven't been using Python very long, only about six months or so. When 
I started I  look at a number of different IDE, and settled on Spyder, 
although not in Anaconda.  I just installed Canopy in order to use the 
ipython notebook, and the code ran perfectly in the Canopy editor!!!!  
Perhaps I should switch IDE's, but I rather like the Variable Explorer 
feature in Spyder.
