Can someone please convert this matlab script to python code?

function [gradient, or] = canny(im, sigma, scaling, vert, horz)

xscaling = vert; yscaling = horz;

hsize = [6*sigma+1, 6*sigma+1]; % The filter size.

gaussian = fspecial('gaussian',hsize,sigma);

im = filter2(gaussian,im); % Smoothed image.

im = imresize(im, scaling, 'AntiAliasing',false);

[rows, cols] = size(im);

h = [ im(:,2:cols) zeros(rows,1) ] - [ zeros(rows,1) im(:,1:cols-1) ];

v = [ im(2:rows,:); zeros(1,cols) ] - [ zeros(1,cols); im(1:rows-1,:) ];

d1 = [ im(2:rows,2:cols) zeros(rows-1,1); zeros(1,cols) ] - ...

[ zeros(1,cols); zeros(rows-1,1) im(1:rows-1,1:cols-1) ];

d2 = [ zeros(1,cols); im(1:rows-1,2:cols) zeros(rows-1,1); ] - ...

[ zeros(rows-1,1) im(2:rows,1:cols-1); zeros(1,cols) ];

X = ( h + (d1 + d2)/2.0 ) * xscaling;

Y = ( v + (d1 - d2)/2.0 ) * yscaling;

gradient = sqrt(X.*X + Y.*Y); % Gradient amplitude.

or = atan2(-Y, X); % Angles -pi to + pi.

neg = or<0; % Map angles to 0-pi.

or = or.*~neg + (or+pi).*neg;

or = or*180/pi; % Convert to degrees.
