Python Set Data Type

Python Set Data Type

# A set is an unordered collection of items. Every element is unique (no duplicates) and must be immutable (which cannot be changed). # # Operators for Sets # Sets and frozen sets support the following operators: # # key in set-example       # containment check # # key not in set-example   # non-containment check # # set-1 == set-2       # set-1 is equivalent to set-2 # # set-1 != set-2       # set-1 is not equivalent to set-2 # # set-1 <= set-2       # set-1is subset of set-2 set-1 < set-2     # set-1 is proper subset of set-2 set-1 >= set-2    # set-1is superset of set-2 # # set-1 > set-2        # set-1 is proper superset of set-2 # # set-1 | set-2        # the union of set-1 and set-2 # # set-1 & set-2        # the intersection of set-1 and set-2 # # set-1 - set-2        # the set of elements in set-1 but not set-2 # # set-1 ^ set-2        # the set of elements in precisely one of set-1 or set-2 # set1=set('abc') set2=set('bcd') output=set1|set2 print ("Output for : ", end="") print (output) print("Set1 = ", set1) print("Set2 = ", set2) print("\n") # Union of set1 and set2 set3 = set1 | set2# set1.union(set2) print("Union of Set1 & Set2: Set3 = ", set3) # Intersection of set1 and set2 set4 = set1 & set2# set1.intersection(set2) print("Intersection of Set1 & Set2: Set4 = ", set4) print("\n") # Checking relation between set3 and set4 if set3 > set4: # set3.issuperset(set4) print("Set3 is superset of Set4") elif set3 < set4: # set3.issubset(set4) print("Set3 is subset of Set4") else : # set3 == set4 print("Set3 is same as Set4") # displaying relation between set4 and set3 if set4 < set3: # set4.issubset(set3) print("Set4 is subset of Set3") print("\n") # difference between set3 and set4 set3 = set1 - set2 print("Elements in Set1 and not in Set2: Set3 = ", set3) print("\n") # check if set4 and set5 are disjoint sets if set1.isdisjoint(set2): print("Set1 and Set2 have nothing in common\n") # Removing all the values of set5 set1.clear() print("After applying clear on sets Set5: ") print("Set1 = ", set1)
