Translate the MATLAB code to Python.

Need the Python code.

N = 10; ILidiagonal matrix A = ones (N,3).*[1,-4,1]; ) D = ones (N,1).*-2; Boundary Conditions A(1, :) = A, [0,-1,0]; A(end, :) = [0,-1,0]; = = D(1) = -1; D(end) = -1; uz u = thomas3 (A, D, N); function x = thomas 3 (A, D, n) Extract columns a = A(:,1); b = A(:, 2); C = A(:,3); d =D; Initialize bar variables b_b = zeros (n,1); c_b = zeros(n,1); d_b = zeros (n,1); Initial Conditions for bar variables b_b(1) = 5(1): c_b (1) = c(1); d b(1) d (1); Calculate bar variables for i = 2:n b_b(i) = b(i) - (a (i)*c_b(i-1)/b_b(i-1)); c_b(i) c(i); 22 d_b(i) d(i) - (a(i)*d_b(i-1)/b_b(i-1)); end Initial condition for X x (n) = d_b(n)/b_b(n); i = n-1; Calculate X while (i >= 1) x(i) - (d_b(i)-(c_b(i)*x(i+1)))/b_b(i); i = i-1; end end
