By iterative method to get unique elements from tuples
In this method, a loop can be used to store the unique values in a list and then converting that list into tuple.
Python3
# function for iteration and finding unique valuesdef unique_numbers(numbers): un = [] for num in numbers: if num not in un: un.append(num) # to convert list into tuple using tuple() function unique_tuple = tuple(un) return unique_tuple# print the unique tuple by extracting all the unique elementsnumbers = (1, 2, 3, 4, 2, 2, 2, 1, 5, 4, 3, 4, 3)print(unique_numbers(numbers)) |
Output
(1, 2, 3, 4, 5)
The time complexity of this function is O(n^2), because the “in” operator in the if statement has a time complexity of O(n) and it’s used n times in the for loop.
The space complexity is O(n), because the maximum space required by the un list is n (when all elements in the input numbers are unique).
Find Unique Elements from Tuple in Python
Tuples are immutable built-in data type in Python that can store multiple values in it. Extracting Unique Elements from a Tuple in Python can be done through two different approaches.
Examples:
Input: (1, 2, 13, 4, 3, 12, 5, 7, 7, 2, 2, 4)
Output: (1, 2, 3,4,5,12,13)
Input: ('Apple', 'Mango', 'Banana', 'Mango', 'Apple')
Output: ('Apple', 'Mango', 'Banana')
