How do I deduplicate tuples in Python safely and idiomatically?

In Python, you can deduplicate tuples using various methods. A common idiomatic way is to convert the list of tuples into a set and then back to a tuple to remove duplicates. However, sets do not maintain the order of elements, so if order is important, you can use a combination of a loop and a set for tracking duplicates.

Here's a simple example that demonstrates how to safely deduplicate a list of tuples while retaining the original order:

list_of_tuples = [(1, 2), (3, 4), (1, 2), (5, 6), (3, 4)] seen = set() deduplicated = [] for item in list_of_tuples: if item not in seen: seen.add(item) deduplicated.append(item) print(deduplicated) # Output: [(1, 2), (3, 4), (5, 6)]
