Remove Duplicates from Array in Python

Hello everyone
In Python, I'm working to find a solution to the duplicates in an array issue. Online, I have discovered a few solutions, but I'm not sure which is the most effective. The blog I referred to Remove Duplicates from Array in Python
Using a set is one option. A data structure known as a set exclusively stores singular components. In order to generate an array without duplicate elements, we can first create a set of the array's items.
def remove_duplicates(array): seen = set() new_array = [] for element in array: if element not in seen: seen.add(element) new_array.append(element) return new_array
Utilising a hash table is a further remedy. A data structure that associates keys with values is a hash table. To convert each element in the array into a different number, we can utilise a hash table. Then, using iteration, we may add elements to the new array from the hash table that have unique numbers alone.
def remove_duplicates(array): seen = {} new_array = [] for element in array: if element not in seen: seen[element] = 1 new_array.append(element) return new_array
Which approach is the most effective among these? Is there a more effective approach in Python to eliminate duplicates from an array?

Hi. This forum is not necessarily the best for generic Python questions.Either of your techniques is standard.
set()
might be the most efficient.If you are using numpy it offers a NumPy: numpy.unique() function to save you writing the code.
