np.add(x1, x2) # 返回 array([[ 0., 2., 4.], [ 3., 5., 7.], [ 6., 8., 10.]]) #substract使用,The difference of x1 and x2, element-wise. Returns a scalar if both x1 and x2 are scalars. np.subtract(1.0, 4.0) # 返回 -3.0,两个都是标量则返回标量 x1 = np.arange...
Thenp.add.at() function in Pythonis a specialized method offered by NumPy. This is used to perform element-wise operations on arrays. Theadd.at()method provides a way to perform unbuffered in-place addition on an array at specified indices. NumPy add.at() function’s syntax The basic syn...

Use the np.where "ufunc" to create a new array result_array based on the condition applied to condition_array. If the condition is True, the corresponding element from ‘array_1’ is chosen; otherwise, the element from ‘array_2’ is chosen. Print Results: Print the original arrays ...
Converting Python array_like Objects to NumPy Arrays 整体来说,我们可以使用numpy.array()函数将 Python 中任何以类似数组方式组织的数值数据转化成 numpy.ndarray。最显而易见的例子是 list 和 tuple3。 有一些对象支持 array-protocol,因此我们也可以使用 numpy.array() 函数将这些对象转换成 numpy.array。最简...
