Answer 1

my_set.remove((6, 7))

The remove() method can be used to remove items from a set.

Answer 2

If you've got a list of those tuples you can clear it out like this:

l = [(1,2),(3,4),(5,6)]

[(1, 2), (3, 4), (5, 6)]
l.remove((3,4))
[(1, 2), (5, 6)]

Answer 3

You can use remove():

>>> s = set([1, 2, 3])
>>> s.remove(2)
>>> s
set([1, 3])

Answer 4

a -= set([(6, 7)])
