The intersection() method returns a new set with elements that are common to all sets.

The intersection of two or more sets is the set of elements which are common to all sets. For example:

A = {1, 2, 3, 4} B = {2, 3, 4, 9} C = {2, 4, 9 10} Then, A∩B = B∩A ={2, 3, 4} A∩C = C∩A ={2, 4} B∩C = C∩B ={2, 4, 9} A∩B∩C = {2, 4}

The syntax of intersection() in Python is:

A.intersection(*other_sets)

The intersection() allows arbitrary number of arguments (sets).

**Note:** `*` is not part of the syntax. It is used to indicate that the method allows arbitrary number of arguments.

The intersection() method returns the intersection of set `A` with all the sets (passed as argument).

If argument is not passed to intersection(), it returns a shallow copy the set (`A`).

A = {2, 3, 5, 4} B = {2, 5, 100} C = {2, 3, 8, 9, 10} print(B.intersection(A)) print(B.intersection(C)) print(A.intersection(C)) print(C.intersection(A, B))

When you run the program, the output will be:

{2, 5} {2} {2, 3} {2}

A = {100, 7, 8} B = {200, 4, 5} C = {300, 2, 3} D = {100, 200, 300} print(A.intersection(D)) print(B.intersection(D)) print(C.intersection(D)) print(A.intersection(B, C, D))

When you run the program, the output will be:

{100} {200} {300} set()

You can also find the intersection of sets using `&` operator

A = {100, 7, 8} B = {200, 4, 5} C = {300, 2, 3, 7} D = {100, 200, 300} print(A & C) print(A & D) print(A & C & D) print(A & B & C & D)

When you run the program, the output will be:

{7} {100} set() set()
