How to run a python script from another python script and get the returned status code?

I'm relatively new to both Python and bash. However, I am finding Python much more intuitive and easier than bash. I have a few bash scripts I have managed to cobble together, but I would like to replace them with Python scripts - for ease of maintenance etc.

The bash scripts essentially run python scripts, check the returned status code and act appropriately (e.g. log a message, fire off an email etc) - this is functionality that I thing I can for the most part, reproduce in a Python script.

The one thing I am not sure of how to do, is how to run a python script from another python script and get the returned status code.

Can anyone post a snippet here that will show how to run a small python script 'test.py' from a main python script 'master.py' and correctly retrieve the return code after running test.py from master.py?

I would suggest you to look at the subprocess module in python. You can start another process using it, manipulate its streams and get the return code.

Using subprocess module

master.py

import subprocess
retcode = subprocess.call(["/usr/bin/python", "/path/to/test.py"])
print "Return code of test.py is ", retcode
