18 gru 2017 · This article demonstrates different operations on Python sets. Examples: Input : A = {0, 2, 4, 6, 8} B = {1, 2, 3, 4, 5} Output : Union : [0, 1, 2, 3, 4, 5, 6, 8] Intersection : [2, 4] Difference : [8, 0, 6] Symmetric difference : [0, 1, 3, 5, 6, 8] In Python, below quick operands can be used for different operations. | for union.

From Python version 2.6 on you can use multiple arguments to set.intersection(), like. u = set.intersection(s1, s2, s3) If the sets are in a list, this translates to: u = set.intersection(*setlist) where *a_list is list expansion

28 kwi 2022 · The intersection of two sets is the set of all the elements that are common to both sets. In Python, you may use either the intersection() method or the & operator to find the intersection. Here are some Python intersection examples: Using the & operator:
In Python, you can use the set intersection() method or set intersection operator (&) to intersect two or more sets: new_set = set1.intersection(set2, set3) new_set = set1 & set2 & set3. The intersection () method and & operator have the same performance.
intersection() method returns the intersection of set A with all the sets (passed as argument). If the argument is not passed to intersection(), it returns a shallow copy of the set (A).
You can specify multiple sets with the intersection method and operator, just like you can with set union: Python >>> a = { 1 , 2 , 3 , 4 } >>> b = { 2 , 3 , 4 , 5 } >>> c = { 3 , 4 , 5 , 6 } >>> d = { 4 , 5 , 6 , 7 } >>> a . intersection ( b , c , d ) {4} >>> a & b & c & d {4}
