![]() ![]() Accordingly, sets do not support indexing, slicing, or Being an unordered collection, sets do not record element position or Like other collections, sets support x in set, len(set), and for x in set. Operations on sets such as intersection, union, difference, and symmetric Testing, removing duplicates from a sequence, and computing standard math Unordered collections of unique elements. The sets module provides classes for constructing and manipulating To remove all the elements from the set, clear() function is used.Deprecated since version 2.6: The built-in set/ frozenset types replace this module. Note – If the set is unordered then there’s no such way to determine which element is popped by using the pop() function. Pop() function can also be used to remove and return an element from the set, but it removes only the last element of the set. Print("nSet after Removing a range of elements: ") Print("nSet after Discarding two elements: ") Print("nSet after Removal of two elements: ") To remove elements from a set without KeyError, use discard(), if the element doesn’t exist in the set, it remains unchanged. Using remove() method or discard() methodĮlements can be removed from the Set by using built-in remove() function but a KeyError arises if element doesn’t exist in the set. But you can loop through the set items using a for loop, or ask if a specified value is present in a set, by using the in keyword. Set items cannot be accessed by referring to an index, since sets are unordered the items has no index. Set after Addition of elements using Update: Print("nSet after Addition of elements using Update: ") In all of these cases, duplicate elements are avoided. The update() method accepts lists, strings, tuples as well as other sets as its arguments. Print("nSet after Addition of elements from 1-5: ")įor addition of two or more elements Update() method is used. Print("nSet after Addition of Three elements: ") ![]() Note – Lists cannot be added to a set as elements because Lists are not hashable whereas Tuples can be added because tuples are immutable and hence Hashable. Only one element at a time can be added to the set by using add() method, loops are used to add multiple elements at a time with the use of add() method. Print("nSet with the use of Mixed Values")Įlements can be added to the Set by using built-in add() function. Type of elements in a set need not be the same, various mixed up data type values can also be passed to the set. Order of elements in a set is undefined and is unchangeable. Print("nSet with the use of an Object: " )Ī set contains only unique elements but at the time of set creation, multiple duplicate values can also be passed. Note – A set cannot have mutable elements like a list, set or dictionary, as its elements. Sets can be created by using the built-in set() function with an iterable object or a sequence by placing the sequence inside curly braces, separated by ‘comma’. The major advantage of using a set, as opposed to a list, is that it has a highly optimized method for checking whether a specific element is contained in the set. The order of elements in a set is undefined though it may consist of various elements. In Python, Set is an unordered collection of data type that is iterable, mutable and has no duplicate elements.
