python - How can I use subprocess.Popen to run a method in another file while passing in multiple dictionaries? -

p = subprocess.popen(['python2.7', 'from some.path.foo import run_setup', 'import ast',                       'nsvs = ' + str(new_system_variables), 'nsv = ast.literal_eval(nsvs)',                       'us = ' + str(user_dict), 'u = ast.literal_eval(us)',                       'run_setup(nsv, u)'], stdout=subprocess.pipe, stderr=subprocess.pipe) 

above code. need have run_setup method run in background. run_setup in fact run current implementation, none of values in dictionaries seem passed in. new_system_variables , user_dict being 2 dictionaries i'm trying pass in. in advance!

use multiprocessing instead;

from multiprocessing import process some.path.foo import run_setup  p = process(target=run_setup, args=(new_system_variables, user_dict)) p.start() p.join()
