‘x = np.array(...)’ creates a 2D NumPy array 'x' with the given elements. ‘np.isnan(x)’ creates a boolean array with the same shape as 'x', where each element is True if the corresponding element in 'x' is NaN and False otherwise. np.isnan(x).any(axis=1): Use the a...

Remove Nan Values Using theisfinite()Method in NumPy As the name suggests, theisfinite()function is a boolean function that checks whether an element is finite or not. It can also check for finite values in an array and returns a boolean array for the same. The boolean array will store...
