python launcher doesn't work

[dboxall1234]

hi
i've recently been learning about python on cssciencecircles.com. After a while i decided to download it so i can save some of my programmes. When i make a programme in the IDLE shell and save it, even the most simple instructions, eg. print('hello world') , when i try to open it in the launcher it says: -bash: :command not found.
Not really sure what i'm doing wrong. I have a mac osx 10.6.8 and am running python 3.2.3. Any ideas?
Thanks
Dan
