Conversion matlab code to python code

I want to convert matalb code to python code.

But I am having difficulty converting the code so, leave a question.

IM = load_nii(uigetfile('*.nii','Select the Analyze file format'), [], [], [], [], [], 1); % Load 3D CT Image
movingVolume = flipud(IM.img);
spineVolume = movingVolume;
[row,col,slice] = size(movingVolume);

for z=1:slice
    for i=1:row
        for j=1:col
            if j < 330
                movingVolume(i,j,z) = -1;
            end
        end
    end
end

for z=1:slice
    for i=1:row
        for j=1:col
            if movingVolume(i,j,z) > -800 
                movingVolume(i,j,z) = 1;
            else 
                movingVolume(i,j,z) = 0;
            end
        end
    end
end

It looks like you've already done the conversion and since you don't tell us anything about the original code we can't tell if it's correct or not. You also don't ask a question, so it's unclear what you want.

The code you have written can be greatly simplified:

IM = load_nii(uigetfile('*.nii','Select the Analyze file format'), [], [], [], [], [], 1); % Load 3D CT Image
movingVolume = flipud(IM.img);
spineVolume = movingVolume;   %not sure what the purpose of that is. You don't show SpineVolume being used
movingvolume(:, 1:329, :) = -1;      %replace your first loop
movingvolume = movingvolume > -800;  %replace your 2nd loop

Some small edits for edge cases:

IM = load_nii(uigetfile('*.nii','Select the Analyze file format'), [], [], [], [], [], 1); % Load 3D CT Image
movingVolume = flipud(IM.img);
spineVolume = movingVolume;   %not sure what the purpose of that is. You don't show SpineVolume being used
movingvolume(:, 1:min(329,end), :) = -1;      %replace your first loop
movingvolume = double(movingvolume > -800);  %replace your 2nd loop
%or possibly: movingvolume = cast(movingvolume > -800,'like',movingvolume);
