Python NumPy nanmean() function is used to compute the arithmetic mean or average of the array along a specified axis while ignoring NaN (Not a Number)
print(np.unique(x)): The np.unique function returns the sorted unique elements of the input array x. In this case, the unique elements are 10, 20, and 30, so the output will be [10 20 30]. x = np.array([[ 1, 1], [2, 3]]): Creates a 2x2 NumPy array with elements 1, ...
