Session 4.2

There is a typo in the last example of Session 4.2.  The variable throughout this entire example is called mylist (all lowercase letters).  The last two lines show a variable myList with an uppercase L.  This will be an error in Python since it is case sensitive.  The variable should be named mylist.  This error also occurred in the 1st edition.  Thanks to Phillip and Marisol for catching this one.
