numpy ndarray search index
numpy.where() is my favorite. >>> x = numpy.array([1,0,2,0,3,0,4,5,6,7,8]) >>> numpy.where(x == 0)[0] array([1, 3, 5]). ,You can convert a numpy array to list and get its index . Both take the same number of characters, but the first method returns an int instead of a numpy.ndarray . First array in output depicts the row index and second array depicts the corresponding colu
