Answer 1

It should be #!/usr/bin/python not user

To find the full path of your python interpreter, run this command which python and it'll give you something like /usr/bin/python .

Answer 2

Correct one is :

for python 2x

#!/usr/bin/env python
   ^^^
  usr not user        

for python 3x

#!/usr/bin/env python3       

you also need to give your file executable permission

chmod u+x test.py
