1, 1], [2, 3]]): Creates a 2x2 NumPy array with elements 1, 1, 2, and 3. print(np.unique(x)): The np.unique function works with multi-dimensional arrays as well. It flattens the input array and then returns the sorted unique elements. In this case, the unique elements are ...
To get unique values in an array, we can use the NumPy unique function in Python. This identifies elements in an array, with options for additional functionality. Its basic use returns sorted unique values, but parameters like return_index, return_inverse, and return_counts provide indices, inv...

In the above code we first create a 2D array 'x' using the np.array() method with the values [[1, 1], [2, 3], [3, 4]]. Then, the np.unique() function is used to find the unique elements in the array 'x'. Since 'x' is a 2D array, np.unique() treats it as a flat...
