Use python set to compare django querysets

queryset_compare.py

"""
First technique, use set
"""
# two querysets or lists
q1
>>> [<obj1>,<obj2>, <obj3>]
q2
>>> [<obj4>,<obj2>, <obj5>]

# compare querysets :
set(q1) == set(q2)
>>> False

# get objects present in both
set(q1).intersection(set(q2))
>>> <obj2>

# get objects of q1 not in q2
set(q1).difference(set(q2))
>>> <obj1> <obj3>

# vice versa
set(q2).difference(set(q1))
>>> <obj4> <obj5>


"""
Second technique, use exclude / filter
"""

Where is the second technique?
