Is it possible to run function in a subprocess without threading or writing a separate file/script.

import subprocess def my_function(x): return x + 100 output = subprocess.Popen(my_function, 1) #I would like to pass the function object and its arguments print output #desired output: 101 I have only found documentation on opening subprocesses using separate scripts. Does anyone know how to pass function objects or even an easy way to pass function code?
I think you're looking for something more like the multiprocessing module: http://docs.python.org/library/multiprocessing.html#the-process-class The subprocess module is for spawning processes and doing things with their input/output - not for running functions. Here is a multiprocessing version of your code: from multiprocessing import Process, Queue # must be a global function def my_function(q, x): q.put(x + 100) if __name__ == '__main__': queue = Queue() p = Process(target=my_function, args=(queue, 1)) p.start() p.join() # this blocks until the process terminates result = queue.get() print result
