Hi, the parameter list should be a list of strings, not several unpacked 
strings :

     command = ["/root/Desktop/abc.py","64","abc"]
     proc1 = subprocess.Popen(command, shell=True, 
stdout=subprocess.PIPE, stderr=subprocess.PIPE)

Also, be sure to use a shebang like "#!/usr/bin/env python" at the 
beginning of abc.py or your environment may be unable to find out that 
you want to execute that script with Python. Or better, you can call 
that script directly with Python :

     command = ["python","/root/Desktop/abc.py","64","abc"]
