Most Basic Question Ever - please help

[seanm.py at gmail.com]

I am going to try posting here again with more detail to see if I can
finally get my first program to work.

I am working on a MacBook Pro with OS X 10.4.11. I opened a new window
in IDLE to create a file. The file had only one line of code and was
saved as module1.py. I saved it to Macintosh HD. The one line of code
in the file is copied below:

print 'Hello module world!'

I closed the file and tried to run it in IDLE and Terminal, but I have
had no success. I'll paste my commands and the error messages below
(for IDLE, then Terminal). Any help would be very much appreciated. I
feel like the marathon just started and I've fallen flat on my face.
Thanks.
