I usually do python example.py in terminal for execution. Can we do this in Java? Can we launch a python script from java ? Because I want to launch some python commands from my website Java EE. I don't mean to execute the python code in java, but just let java to call python to do it.

example.py

print "hello world"

Is it possible ? Where should I get started ?
