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);
