How do I deduplicate lists in Python using NumPy?

Deduplicating lists in Python can be efficiently achieved using NumPy. This method leverages the unique capabilities of NumPy arrays to eliminate duplicate values from a list while maintaining performance.

Example


        import numpy as np

        # Sample list with duplicates
        original_list = [1, 2, 2, 3, 4, 4, 5]

        # Convert the list to a NumPy array and use np.unique
        unique_array = np.unique(original_list)

        # Convert back to list if needed
        unique_list = unique_array.tolist()

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