Hello everyone. I have a program which performs the 2d Shannon interpolation for different random variables. I have to send that code to another person who uses python. For that, and with help from people of this forum I built the following code, which construct the Shannon interpolation for each random variable as a row of a text file and then replaces the Mathematica output to look like a Python's. The problem is that for each random variable I need to separate the look of the output. My current code alters all the rows equally. I would need to change the string replace to make each row have it's number, but I haven't seen any option to do this in the documentation.

The Shannon interpolation is as follows:

savedX = Table[XposX = aaa[[All, 1]]; YposX = aaa[[All, 2]]; 
   windXVal = aaa[[All, i]];
   windXMat = Transpose[{XposX, YposX, windXVal}];
   ifuncEPSX = Interpolation[windXMat //. {x_List} :> x];
   intDataVectorEPSX = 
    Flatten[Table[{t, u, ifuncEPSX[t, u]}, {t, xmin, xmax, 
       dDeltaX}, {u, ymin, ymax, dDeltaY}]];
   leEPSX = Length@intDataVectorEPSX;
   vectorXintEPSX = 
    Table[intDataVectorEPSX[[i]], {i, 1, leEPSX - 2, 3}];
   vectorYintEPSX = 
    Table[intDataVectorEPSX[[i]], {i, 2, leEPSX - 1, 3}];
   vectorFintEPSX = Table[intDataVectorEPSX[[i]], {i, 3, leEPSX, 3}];
   interpolatedDataEPSX = 
    Transpose[{vectorXintEPSX, vectorYintEPSX, vectorFintEPSX}];
   Total[#3*sinc[(t - #1)/dDeltaX]*sinc[(u - #2)/dDeltaY] & @@@ 
     interpolatedDataEPSX], {i, 3, countMax + 2}];

And the string replace

Export["savedWindX.txt", savedX]
savedXPython = Import["savedWindX.txt"] // StringReplace[#, {"[" -> "(", "]" -> ")", "t" -> "m.lammda[i]*180/np.pi", "u" -> "m.phi[i]*180/np.pi"}] &

What I need is to replace t by m.lammda1[i]180/np.pi on the first row, m.lammda2[i]180/np.pi in the second and so on; same thing for m.phi.

Is there a way to do this? Regards. Jaime
