How to get unique elements in nested tuple in Python

When it is required to get the unique elements in a nested tuple, a nested loop and the 'set' operator can be used.

Python comes with a datatype known as 'set'. This 'set' contains elements that are unique only.

The set is useful in performing operations such as intersection, difference, union and symmetric difference.

Below is a demonstration of the same −

Example

Live Demo

my_list_1 = [(7, 8, 0), (0 ,3, 45), (3, 2, 22), (45, 12, 9)]

print ("The list of tuple is : " )
print(my_list_1)

my_result = []
temp = set()
for inner in my_list_1:
   for elem in inner:
      if not elem in temp:
         temp.add(elem)
         my_result.append(elem)
print("The unique elements in the list of tuples are : ")
print(my_result)

Output

The list of tuple is :
[(7, 8, 0), (0, 3, 45), (3, 2, 22), (45, 12, 9)]
The unique elements in the list of tuples are :
[7, 8, 0, 3, 45, 2, 22, 12, 9]

Explanation

  • A list of tuple is defined, and is displayed on the console.
  • An empty list is created, and an empty set is created.
  • The list is iterated through, and checked to see if it is present in the list.
  • If not, it is added to the list as well as the empty set.
  • This result is assigned to a value.
  • It is displayed as output on the console.
