No idea what you mean by "load a class."

You can create an object by the classname and parentheses, containing 
the paramters as specified in the __init__() method.  So since your 
class was called QB (which should be Qb, by naming conventions):

obj = QB("Joe", "Montana", "415-213-4567",

joe.montana at gmail.com","Candlestick Park")

and since that happens to be one element of your list, you could use

obj = QB( *QB_list[0] )

If you want a collection of such objects, you might want to write a loop, and then indeed the append method might be useful.

Write some code, and show us where you get stuck.
