is it possible to use matlab to produce tuples in python?

i've been using this to write variables into a .py file then opening this file in the main script (the script creates a model in the finite element solver ABAQUS and python is the only language it understands)

GridSpaceX=1;

%Make python file with variables

delete('Var.py');

fid = fopen('Var.py', 'w');

fprintf(fid,'GridSpaceX = %0.12f\n',GridSpaceX);

but for one of the variables I need to create a python tuple and all i have is a matlab matrix. any help would be greatly appreciated. Thanks for your help, Michael p.s. a tuple is an immutable list and the matrix is a 2 by lots matrix that is created by matlab

Hi,

You can write a MATLAB script to convert a MATLAB matrix into a Python tuple and then write that tuple to a ".py" file. Below is an example of how you can achieve this.

GridSpaceX = 1;
Matrix = [1, 2, 3; 4, 5, 6]; 

% Convert the matrix to a Python-compatible tuple string
tuple_str = '(';
for i = 1:size(Matrix, 2)
    tuple_str = strcat(tuple_str, '(', num2str(Matrix(1, i)), ',', num2str(Matrix(2, i)), '),');
end
tuple_str(end) = ')';

% Make python file with variables
delete('Var.py');
fid = fopen('Var.py', 'w');
fprintf(fid, 'GridSpaceX = %0.12f\n', GridSpaceX);
fprintf(fid, 'MatrixTuple = %s\n', tuple_str);
fclose(fid);

Hope it helps.
