如果是类似一维数组,则返回向量(1D-array,不存在行、列之分,shape都是(n,)而非(n,1),因此其转置不会变为1xn的2D-array),如果list类似二维数组,则返回2D-array。1D-array可通过reshape转为2D-array,或者.array()时令ndmin=2。 np.array(['one', 'dim', 'list'])-> 1D-array np.array([],[],.....

Return the largest integer smaller or equal to the division of the inputs. 6)numpy.power numpy.power(x1, x2, *args, **kwargs) First array elements raised to powers from second array, element-wise. 1. 2. 3. 4. 5. 6. 7.
The divide() function is used to perform element-wise division of the elements in two arrays. The divide() function performs element-wise division of the elements in two arrays i.e., the elements of the numerator array are divided by the corresponding el
