In the interest of preferred techniques, your loop will be more pythonic
when you write this part...
> len_Qb_list = len(Qb_list) # Get the lenght of the list of
> lists which is the
> # number of rows in the input data
> for i in range(0, len_Qb_list): # Iterate for the number of rows
> nq = Qb(*Qb_list[i]) # Create an instance of class Qb called "nq"
> # and populate each field
> quarterbacks.append(nq) # Append an instance of object
> "nq" into object list "quarterbacks"
> i = i + 1 # Iterate for each row in "Qb_list"
for this_qb in Qb_list: # Iterate over Qb_list
quarterbacks.append(Qb(*this_qb)) # append Qb instance to quarterbacks
...or even drop the quarterbacks declaration above...
quarterbacks = [Qb(*this_qb) for this_qb in Qb_list
> print (quarterbacks.phone) # Print an item from the object
> list "quarterbacks"
> print (Qb_list) # Print the same object from the
> original list of lists
