How to run python script in linux Executable shell

Question

I Have a python script ready and I need to run using Hudson CI. I can see configure job having the only environment supported is an executable shell. How can I run a python script in the executable shell (Bash shell)? any idea or suggestions?

Answer 1

python3

python3 file.py

python2

python file.py

Answer 2

Aside from the obvious python3 file.py or python file.py, it is possible to make the python file executable on its own by introducing an appropriate shebang at the top:

#!/usr/bin/env python3
...
(script follows here)

or

#!/usr/bin/env python
...
(script follows here)

Using these, your CI doesn't need to know that the script is written in python, in shell, in perl or whatever language it uses.
