Since you don't tell us what you are doing, we cant tell you what about it is wrong. If you are are trying to execute HW.py from the >>> prompt by just typing its name then that's wrong. You need to import it as HW import HW # note not HW.py, just HW And if it has a sentinel section that runs a main() function then you need to replicate that code manually. But it's not normal to run programs from the Python shell like that. Most IDEs such as IDLE have a menu option to run the program and the output then appears in the shell window. But, even then, it should just be for testing, the best way to run the program is, as you apparently did, using the python interpreter directly from the OS. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
