<\/h3>\nA set is an unordered collection of mixed data types. No duplicates can be there in a set. Sets are declared by enclosing the items in curly brackets with each item separated by a comma.<\/p>\n
<\/h3>\nThe following operators work on sets<\/p>\n
They are examined in detail below:<\/p>\n
in – membership<\/strong><\/p>\n Checks if an item exists in the set<\/p>\n len – length of set<\/strong><\/p>\n Returns the length of a set. If set has no items then the length is zero<\/p>\n \u00a0| – logical or set1 | set2<\/strong><\/p>\n Combines items of set1 and set2 to create a new set with all the elements of both the sets. Duplicates are ignored<\/p>\n & – logical and set1 & set2<\/strong><\/p>\n Combines items of set1 and set2 to create a new set with only the common elements in both the sets<\/p>\n \u00a0– minus \u00a0set1 – set2<\/strong><\/p>\n Returns all the items in set1 which are not in set2<\/p>\n <= equivalence set1 <= set2<\/strong><\/p>\n Checks whether all items in set1 are in set2<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Sets also support methods which are the same as their mathematical counterparts, which are shown below:<\/p>\n union – set1.union(set2)<\/strong><\/p>\n Returns elements from both set1 and set2. Duplicates are ignored<\/p>\n intersection – set1.intersection(set1)<\/strong><\/p>\n Returns only common elements from both set1 and set2.<\/p>\n difference – set1.difference(set2)<\/strong><\/p>\n Returns elements in set1 which are not in set2.<\/p>\n issubset – set1.issubset(set2)<\/strong><\/p>\n Returns True if all elements of set1 are in set2, else False<\/p>\n add – set1.add(item)<\/strong><\/p>\n Adds an item to a set. If an item already exists it is not added<\/p>\n remove – set1.remove(item)<\/strong><\/p>\n Removes an item from the set. If item does not exist then an error is thrown<\/p>\n pop – set1.pop()<\/strong><\/p>\n Removes an arbitrary item from the set. Since a set is not ordered, there is no guarantee on which item will be removed<\/p>\n clear – set1.clear()<\/strong><\/p>\n Removes all the elements from a set<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n The last collection we will look at are dictionaries<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"![\"\"](\"https:\/\/truelogic.org\/wordpress\/wp-content\/uploads\/2018\/03\/set2.png\")
