If you're passing parameters as a list, then you need a "," at the end of the items. Otherwise if you have something like a string as the only item, the list will be the string.

My program models cell reproduction. I have written a program that models this and it works. Now I want to model a tissue with several types of cells. I did this by simply rerunning the program with different inputs (cell characteristics). But now I want to send and receive signals between the cells in each population. This requires some sort of concurrent processing with halts at appropriate points to pass and receive signals. I thought to use multiprocessing. I have read the documentation and reproduced the models in the docs. But I cannot figure out how to feed in the data for multiple parameters. I have tried using Pool and it works fine, but I can only get it to accept 1 input parameter, although multiple data inputs with one parameter works nicely. So, my questions are; 1. Is multiprocessing the suitable choice. 2. if yes, how does one write a function with multiple input parameters. Thank s in advance. Sydney Prodessor.
