Answer 1

You can simply use .remove method for lists when you know the element that is to be removed.

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

Answer 2

Other way, you can use del

>>> a = [(1,2),(2,3),(3,3)]
>>> del a[a.index((1,2))]
>>> a
[(2, 3), (3, 3)]
>>> 

or using .pop

>>> a = [(1,2),(2,3),(3,3)]
>>> a.pop(a.index((1,2)))
(1, 2)
>>> a
[(2, 3), (3, 3)]
>>>
