Python | Test if tuple is distinct
Sometimes, while working with records, we have a problem in which we need to find if all elements of tuple are different. This can have applications in many domains including web development. Let’s discuss certain ways in which this task can be performed.
Method #1 : Using loop
This is a brute force way in which this task can be performed. In this, we just iterate through all tuple elements and put it in set if it’s the first occurrence. During the subsequence occurrence we check in set, if it exists, we return False.
The original tuple is : (1, 4, 5, 6, 1, 4) Is tuple distinct ? : False
Method #2 : Using
set() + len()
In this method, we convert the tuple into a set using set(), and then check it with original tuple length, if matches, means that it was a distinct tuple and returns True.
The original tuple is : (1, 4, 5, 6) Is tuple distinct ? : True
