How do I export 8 lists of S-parameters into one s2p file?

Hello, i have a Program, that measures all the S-Parameters of a 2 Port Network Analyzer and I want to export the data in the s2p format.

The Data is split up in 8 Lists: S11 Imag(inary), S11 Real, S12 Imag, S12 Real, S21I, S21R, S22 I and S22R. Another list contains the Frequencies that get measured. Using python I want to export the data into the s2p format.

Any help would be greatly appreciated.

Thank you for your fast answer!

rfwrite(data, freq, filename) is the function I will have to use, yes. But to be honest, i dont know how to fill in the Parameters. freq is obviusly the frequency, I can store them in my list of frequencies in the parameters of rfwrite. filename is also clear, but i dont know how to transform the data from 8 lists into the data parameter. Do i need to create a "mega list" with all the values and reference it as data? If yes, how?
