How to create 3 dimensions matrix in numpy , like matlab a(:,:,:) . I try to convert matlab code that create 3d matrix to python by use numpy.array and i don't know how to create 3d matrix/array in numpy

Importing the NumPy package enables us to use the array function in python. To create a three-dimensional array, we pass the object representing x by y by z in python, where x is the nested lists in the object, y is the nested lists inside the x nested lists, and z is the values inside each y nested list.
In Python to initialize a 3-dimension array, we can easily use the np. array function for creating an array and once you will print the 'arr1' then the output will display a 3-dimensional array.
Three-dimensional matrices can be created using the zeros, ones, and rand functions by specifying three dimensions to begin with. For example, zeros(2,4,3) will create a 2 × 4 × 3 matrix of all 0s. Here is another example of creating a three-dimensional matrix.
a=np.empty((2,3,5)) creates a 2x3x5 array. (There is also np.zeros if you want the values initialized.)
You can also reshape existing arrays:
a=np.arange(30).reshape(2,3,5) np.arange(30) creates a 1-d array with values from 0..29. The reshape() method returns an array containing the same data with a new shape.
