# Python | How to get unique elements in a nested tuple

Counters | Python Methods and Functions

Method # 1: Using a nested loop + `set()`
The above 2 functionality can be used to solve this particular problem. In this, we iterate over each nested tuple and add to install if the element is encountered for the first time, and validate each element before adding.

Output:

` The original list: [(3, 4, 5), (4, 5, 7), (1, 4 )] Unique elements in nested tuples are: [3, 4, 5, 7, 1] `

Method # 2: Using ` set () + from_iterable () `
A combination of the above functions can be used to solve this problem. This is done in 2 steps, first we flatten the nested list and then find the differences with ` set () `.
