# Python – Unique Tuple Frequency (Order Irrespective)

• Last Updated : 30 Aug, 2020

Given tuple list, extract the frequency of unique tuples in list order irrespective.

Input : test_list = [(3, 4), (1, 2), (4, 3), (3, 4)]
Output : 2
Explanation : (3, 4), (4, 3), (3, 4) makes 1 and (1, 2) is 2nd unique element.

Input : test_list = [(3, 7), (1, 2), (4, 3), (5, 6)]
Output : 4
Explanation : All are different in any order.

Method #1 : Using `tuple() + generator expression + sorted() + len()`
The combination of above functions can be used to solve this problem. In this, we perform the task of sorting using sorted(), to remove order constraint. The len() is used to compute size.

 `# Python3 code to demonstrate working of ``# Unique Tuple Frequency [ Order Irrespective ]``# Using tuple() + list comprehension + sorted() + len()`` ` `# initializing lists``test_list ``=` `[(``3``, ``4``), (``1``, ``2``), (``4``, ``3``), (``5``, ``6``)]`` ` `# printing original list``print``(``"The original list is : "` `+` `str``(test_list))`` ` `# Using tuple() + list comprehension + sorted() + len()``# Size computed after conversion to set``res ``=` `len``(``list``(``set``(``tuple``(``sorted``(sub)) ``for` `sub ``in` `test_list)))`` ` `# printing result ``print``(``"Unique tuples Frequency : "` `+` `str``(res)) `
Output :

```The original list is : [(3, 4), (1, 2), (4, 3), (5, 6)]
Unique tuples Frequency : 3
```

Method #2 : Using `map() + sorted() + tuple() + set() + len()`
The combination of above functions can be used to solve this problem. In this, we perform the task of extending sorting logic and tuple conversion using map(), set() is used to eliminate duplicates and len() is used to find the length of container.

Output :
```The original list is : [(3, 4), (1, 2), (4, 3), (5, 6)]
Unique tuples Frequency : 3
```
