如何在 concurrent.futures.ProcessPoolExecutor 期间将变量 output 存储在 function 中

Question

I am currently trying to store the output obtained in a function during multiprocessing by using concurrent.futures.ProcessPoolExecutor from concurrent.futures built a library of python3 storing the variable as a global variable. But the variable output gets deleted once the process is over. Does anyone has faced the same issue?

Answer 1

with concurrent.futures.ThreadPoolExecutor(max_workers=7) as executor:
    fxReturn = executor.submit(your_function)
    fxReturn.result()

fxReturn will store return value of your_function but to access it you need to use result()
