 some code going to be here....

digest_pool.close()
digest_pool.join()
here i need to proccess the results 

how can i control the result value for every proccess and know to check to which proccess it belongs ,

Answer 1

store the the value of 'i' from the for loop and either print it or return and save it somewhere else. so if a process happens you can check from which process it was by looking at the variable i.

Hope this helps.
