Efficiently Dedupe List in Python

If you’re someone who enjoys combining logic and compactness, list comprehensions are a fantastic way to solve this. You can use a set within the comprehension for a streamlined solution.

Here’s how:

lseparatedOrbList = [1, 2, 2, 3, 4, 4, 5, 5, 5, 6]  
seen = set()  
unique_list = [item for item in lseparatedOrbList if not (item in seen or seen.add(item))]  

print(unique_list)  # Output: [1, 2, 3, 4, 5, 6]  

This method is concise yet elegant and handles the Python dedupe list challenge effectively.
