python - py2app Application closes on open

Question

I wrote a simple ' Hello, World! ' programme in Python 2.7 to play around with py2app. I made the setup.py file and then I ran python setup.py helloWorld.py

Now it created a build folder and a dist folder and inside the dist folder is the .app application of my helloWorld python script.

Now, here is the issues. Everytime that I try to run said .app, it opens and closes instantly.

What is happening? Is it printing Hello, World and then closing too fast for me to see it? Is there a way to prevent it from closing?

Thanks in Advance!
