In this article given List of sets, the task is to write a Python program to perform their intersection.

**Examples:**

Input :test_list = [{5, 3, 6, 7}, {1, 3, 5, 2}, {7, 3, 8, 5}, {8, 4, 5, 3}]

Output :{3, 5}

Explanation :3 and 5 is present in all the sets.

Input :test_list = [{5, 3, 6, 7}, {1, 3, 5, 2}, {7, 3, 8, 5}, {8, 4, 5, 4}]

Output :{5}

Explanation :5 is present in all the sets.

**Method #1 : Using ****intersection() ****+ * operator**

In this, we perform tasks of getting intersection using intersection() and * operator is used to pack all the sets together.

## Python3

`# Python3 code to demonstrate working of` `# Multiple Sets Intersection` `# Using intersection() + * operator` ` ` `# initializing list` `test_list ` `=` `[{` `5` `, ` `3` `, ` `6` `, ` `7` `}, {` `1` `, ` `3` `, ` `5` `, ` `2` `}, {` `7` `, ` `3` `, ` `8` `, ` `5` `}, {` `8` `, ` `4` `, ` `5` `, ` `3` `}]` ` ` `# printing original list` `print` `(` `"The original list is : "` `+` `str` `(test_list))` ` ` `# getting all sets intersection using intersection()` `res ` `=` `set` `.intersection(` `*` `test_list)` ` ` `# printing result` `print` `(` `"Intersected Sets : "` `+` `str` `(res))` |

**Output:**

The original list is : [{3, 5, 6, 7}, {1, 2, 3, 5}, {8, 3, 5, 7}, {8, 3, 4, 5}]

Intersected Sets : {3, 5}

**Method #2 : Using ****reduce()**** + and_ operator**

In this, we perform task of intersection using and_ operator and reduce() does the task of getting all the sets packed together for required operation.

## Python3

`# Python3 code to demonstrate working of` `# Multiple Sets Intersection` `# Using reduce() + and_ operator` `from` `operator ` `import` `and_` `from` `functools ` `import` `reduce` ` ` `# initializing list` `test_list ` `=` `[{` `5` `, ` `3` `, ` `6` `, ` `7` `}, {` `1` `, ` `3` `, ` `5` `, ` `2` `}, {` `7` `, ` `3` `, ` `8` `, ` `5` `}, {` `8` `, ` `4` `, ` `5` `, ` `3` `}]` ` ` `# printing original list` `print` `(` `"The original list is : "` `+` `str` `(test_list))` ` ` `# getting all sets intersection using and_ operator` `res ` `=` `set` `(` `reduce` `(and_, test_list))` ` ` `# printing result` `print` `(` `"Intersected Sets : "` `+` `str` `(res))` |

**Output:**

The original list is : [{3, 5, 6, 7}, {1, 2, 3, 5}, {8, 3, 5, 7}, {8, 3, 4, 5}]

Intersected Sets : {3, 5}
