Explanation
\n
This calculator uses NumPy’s np.unique() function to efficiently find the unique values in a specified column of a DataFrame. NumPy’s implementation is highly optimized and can handle large datasets much faster than pure Python solutions.
\n
The np.unique() function returns the sorted unique elements of an array, providing a fast way to identify distinct values in your data.
