How can I make sure my python exit

[yinglcs at gmail.com]

Hi,

I have a python script:
At the end of the script, I have:

print "Build Done!"

my question is does that mean my python script exits after it prints
"Build done!"

I have a java program which calls this python script. But i run into a
problem in which the python script never returns to the java program
after it performs a system call to execute that python script.
