Executing Python Scripts on Mac using Python Launcher

[David Thomas]

Hello,
This is my first post so go easy on me.  I am just beginning to program using Python on Mac.  When I try to execute a file using Python Launcher my code seems to cause an error in terminal, when I execute the exact same piece of code and run it in windows it seems to execute as exactly intended.
 How can I make my python script to open up correctly using Python Launcher?  I am running 10.7 on my Mac.  I would upload a photo with the error I get but I can't seem to find the upload feature in this group.

Thanks
