How can I remove duplicates from a list using list comprehension in Python?

You can use a set to remove duplicates while using list comprehension. For example:

my_list = [1, 2, 2, 3, 4, 4, 5]
unique_list = list({x for x in my_list})

This will give you [1, 2, 3, 4, 5].

Can you explain how that works?

Sure! The set comprehension {x for x in my_list} creates a set of unique elements from my_list. Then, converting it back to a list gives you the unique values.

Is there a way to maintain the original order of elements?

Yes! You can use a list comprehension with a condition to maintain order:

unique_list = []
[unique_list.append(x) for x in my_list if x not in unique_list]

This keeps the first occurrence of each element.
