Cool, that perfectly solves my problem 🙂 Thank you so much, pyscripter

Hi, with your VarPyth Demo I'm able to create a numpy array, fill it with data, "transfer" it to python, modify the data, "transfer" it back to delphi and use it in delphi without any problems. So far this works perfect. My problem is, that I have to use time series data from a measurement device (I would like to calculate a fft with (numpy / scipy) and do not know on how to transfer my time series data to python. Here is my "Pseudo-Code": procedure TForm1.FormCreate(Sender: TObject); begin var np := Import('numpy'); var np_array: Variant := np.zeros(10); // 'normally this will be at least 96000 elements np_array[0] := 0.00123; np_array[1] := 0.43312; np_array[2] := 0.20033; np_array[3] := 0.00111; ... and so on PythonModule.SetVar('np_array', ExtractPythonObjectFrom(np_array)); end; Of cause this doesn’t work, because np_array contains only one element, and this is my numpy-array that is containing 10 elements each set to 0. I'm looking for a possibility to create a numpy array in Delphi, fill all elements to the appropriate values and then assign the array to a variant, so that I can use the given mechanism to transfer the data into the python world. Maybe there is another (better, mor simple) solution available? Thanks for your help Gerhard
