Python non-ascii error for hashtag -

i'm trying call c executable python script. obviously, c code has '#include's @ start , that's what's giving me error when call c executable python. use subprocess.call call executable follows:

>>> subprocess.call([sys.executable,"motor_control","50","1","50","1"]) 

and following error:

file "motor_control", line 1 syntaxerror: non-ascii character '\xdd' in file motor_control on line 2, no encoding declared; see http://www.python.org/peps/pep-0263.html details 1 

line 1, line 2 etc have '#include's. motor_control executable, has numeric arguments 50, 1, 50, 1. ran motor_control terminal , runs fine. googled lot similar errors other non-ascii characters , did not find answer related '\xdd', hashtag @ '#include'. means nobody getting error @ #include's, means i'm missing basic. i'm not sure what.

some other answers here, example: syntaxerror of non-ascii character mention adding

 # -*- coding: utf-8 -*- 

to start of python script, did not work me. adding

#!/usr/bin/python 

also did not work, mentioned else.

i'm running code on pcduino (c code executed in c_environment pcduino (help here)). python , c independently works fine on hardware. there need differently calling c code having #?

thanks in advance

subprocess.call([sys.executable,"motor_control","50","1","50","1"]) 

the above command translate /usr/bin/python motor_control 50 1 50 1 , executed

so doing passing excutable python interpreter wrong

try this:

subprocess.call(["/pathtoexecutable/motor_control","50","1","50","1"])
