multithreading - Python Multiprocessing Process seems to stop before doing anything -

i having issues multiprocessing.process - when targeting @ simple function, seems function not getting executed. running this:

import multiprocessing, time  def f(length):     time.sleep( length )  p = multiprocessing.process(target=f, args=(1000,)) p.start() time.sleep(0.5) print( p, p.is_alive() ) 

returns

<process(process-5, stopped[1])> false 

using built-in time.sleep on other hand working:

import multiprocessing, time  p2 = multiprocessing.process(target=time.sleep, args=(1000,)) p2.start() time.sleep(0.5) print( p2, p2.is_alive() ) 

gives

<process(process-6, started)> true 

i using spyder 2.3.7/python 3.5.0 64bits on windows sever 2012.
