Suspend and then resume a process in python script - Linux

I am trying to see if there is a way I can suspend and then resume a process in a Python script. I get the process pid using os.getpid() and then I suspend the process using suspend(). Is there a way to resume the process without having to manually type fg in a shell? Here is my code:

-python
#!/usr/bin/env python
import time
import psutil
import os

sm_pid = os.getpid()
p = psutil.Process(sm_pid)

print "Going to suspend"
p.suspend()

time.sleep(5)
p.resume()

print "process resumed"
