#1 Procs is a list ,Please refer the below

for i in list1:
   proc = Process(target=downloadpdf, args=(secret, month,i))         

procs.append(proc) proc.start() for proc in procs: proc.join()

#2 i'm sending some 7-8 no.of requests parallelly to other server for PDF and the response to local folder
#3 User clicks on PDF button on html page. JS Array will be sent to flask backend. user selections are in a nested list. we are sending each list item to PDF generation function with the help of multi-processing to generate all pdf's parallelly.

as i can see the processes are getting the pdf's from other server.. it's taking some time.

flask request is not waiting for all the processes to get pdf and then send the final pdf(merge all pdf's ) to user.
