Set operations:
s.isdisjoint(t)
⇒True→if s has no common itms with t.
⇔s&t→empty set
s.issuperset(t)⇔s greater= t
⇒True→All itms of t is in s.
s greater t⇔s greater= t and s != t
⇒True→s is a proper superset of t.
s.issubset(t)⇔s lesser= t
⇒True→All itms of s is in t.
s lesser t⇔s lesser= t and s != t
⇒True→s is a proper subset of t .

union(), intersection(),

union(t1,...)⇔s | t1 | ...
⇒Returns a new set with itms from s and all others (t1,...)
intersection(t1,...)⇔s & t1 & ...
Returns a new set with itms common to s and all t1,...
difference(t1,...)⇔s - t1 - ...
Returns a new set with itms in s that are not in t1,...
symmetric_difference(t1)⇔s ^ t1
Returns a new set with itms in either s or t1 but not both.

Set Methods: add, remove, discard, pop, clear
Set
→mutable, unordered collection of ',' comma separated unique items within {}
→No support of index, slice or sequence operations.
→ Not Hashable (No nested set) but set items must be Hashable
set creation, set() constructor, set comprehension,
set creation using iterable.
set - unordered, finite sets of unique, immutable objects.
set - unordered collection of distinct hashable objects.
an unordered collection with no duplicate elements.
Uses: membership testing and eliminating duplicate entries. Set objects support mathematical operations like union, intersection, difference, and symmetric difference.

isdisjoint(other)
Return True if the set has no elements in common with other. Sets are disjoint if and only if their intersection is the empty set.
issubset(other)
set lesser= other
Test whether every element in the set is in other.
set lesser other
Test whether the set is a proper subset of other, that is, set lesser= other and set != other.
issuperset(other)
set greater= other
Test whether every element in other is in the set.
set greater other
Test whether the set is a proper superset of other, that is, set greater= other and set != other.
Set Operations
⇒Returns a new set with itms
p=s.union(t1,...)⇔p=s | t1 | ...
⇒From s and all others (t1,...)
p=s.intersection(t1,...)⇔p=s & t1 & ...
⇒Common to s and all t1,...
p=s.difference(t1,...)⇔p=s - t1 - ...
⇒In s that are not in t1,...
p=s.symmetric_difference(t1)⇔p=s ^ t1
⇒In either s or t1 but not both.
p,s→set
Using,
operators:|,&,-,^⇒t1,... must be set
methods:⇒t1,... can be iterable

Set Methods:
itm →immutable type
s.add(itm)→Adds itm but not in any order.
s.remove(itm)→Removes itm if exists else KeyError.
s.discard(itm)→Remove itm if exists otherwise none.
itm=s.pop()→Removes and returns an arbitrary itm.
If empty⇒KeyError
s.clear()→Remove all items⇒set()⇒empty set
Set Creation:
Empty: s=set()
Literals: s={v1,v2}
Iterable: s=set{itr}
Comprehension: s={v for v in itr}
⇒No guarantee in order of items during print or iteration.
MCQ 69-71⇒List Comprehension

frozenset-immutable version of set.
