Call Python from Fortran

Hi, I have a UMAT code in which I need to call a python code and run that python using ABAQUS. I have written these two lines in my UMAT code. str='abaqus cae noGUI=C:\\temp\\Cube.py' and st1=system(str) . However, I have noticed that the python code is not called. I would really appreciate if someone could help me with it.
