Another important point when postring is to always include any error messages(in full) that you get. They contain vital clues as to what is wrong. I see Bob Stepp has replied re the actual code, so I assume his mail reader managed to interpret it correctly - or maybe he just guessed. But following the above guidelines will help you get good answers more quickly in future. -- 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

I'll help you part way. Firstly Python is case sensitive. You have several examples of where you start Python keywords with a capital letter when it should be lowercase. Secondly Python uses indentation (Conventionally 4 spaces.) to segregate code blocks. Thirdly, you won't see the result of your function if you don't print it. So if I correct these in your code I get: def factoria(numb): while numb > 1: if numb==0: return 1 else: result = numb*(numb-1) numb = numb -1 return result print(factoria(5)) But alas! There is more work to be done. This will not give you a syntax error, but now there is an issue with logic error(s). Can you figure it out? It might help if you pretend you are the computer and work out the while loop on paper through each iteration until it exits. Also, when you ask for help you should copy and paste the full traceback of the error you received. What did you get? Did the error relate to anything I corrected above? Unfortunately you won't get a traceback for logic errors! Also give the version of Python and your operating system. I am assuming you are using Python 3.

[Tutor] Using Python to solve factoria
Hello, I really happy to be accepted to the list! This is my current function: def factoria(numb): While numb > 1: If numb==0: return 1 Else: result = numb*(numb-1) numb = numb -1 return result factoria(5) #should output 120 What am I not getting right?
