Explanation / Answer

Please let me know in case of any issue.

1.
Given that s refers to a set, write a statement that attempts to remove the int value 11 from the set, but will do nothing if 11 is not in the set.

   .discard(x)
   This operation also removes element from the set.
   If element does not exist, it does not raise a KeyError.
   The .discard(x) operation returns None.

   s.discard(11);

Given that v has been defined, and that s that refers to a set, write a statement that adds the value referred to by v to set s.
       s.add(v);
3.
Given that v has been defined, and that s that refers to a set, write a statement that adds the value referred to by v to set s.
       s.add(v);
4.
