You have "start-point", but I think that should be "start_point",
judging by the previous line.

I believe that Cobol allows "-"  in names.

Why bother using an actual development tool when you can get an entire
mailing list to be your syntax checker, right?

(With apologies, I initially sent this privately to John, and not to the list.)

As I'm sure you are aware, TextWrangler is the free baby brother of BBEdit which, although not free, contains automatic syntax highlighting for exactly the sort of error you made.  It would have signaled "unmatched parentheses" the instant you finished inputting that line in your original bit of code.  If you value your time, I think you will find it more than pays for itself.

Just saying…

Lisp certainly does.

Though not a lisper, the Python tie-in was my reply:  Python (among
many other languages) doesn't allow a "-" as a character in
identifiers as you appeared to use it in your code.  Unlike HTML,
XML, CSS, and apparently lisp and COBOL (thanks, MRAB, for ripping
open that scab after years of trying to repress those COBOL memories
:-)   where identifiers may contain the dash.

Does BNF count as a language?

I see what you did there, using a dash in your identifier...

And Forth.

Generally speaking, concatenative languages like Forth can use any 
symbols they wish in identifiers, apart from the token separator (usually 
whitespace), since they don't have syntax as we know it in more 
traditional languages.

E.g. in Forth : is the word (command) to start defining a new word, but 
this does not stop you from defining a word called ::: or "foo:bar" (with 
or without the quotes!).

Maybe rename it "defined_start" ;)

I wonder how someone can get to the point of writing more than 76 lines 
of code while not only still making this kind of errors, but not even 
knowing what these errors mean and how to correct them. It's impossible. 
You can't write programs that are more than 10 lines without having 
encountered these errors and learnt how to deal with them.

Unless you're reading exercises from a book, and feeling that you're 
"intermediate", you started reading from chapter 28 in a 29 chapters book.

If you've ever taught programming in a formal teaching setup, you
would not be surprised when students submit C 'projects' that wont
even compile (leave aside segfault).

On a more personal note, the first program I wrote was in Cobol.  I
got only 350 errors before the compiler copped out.  It was a bit
traumatic.  Later on I found I forgot to write
PROCEDURE DIVISION.

So its good to remember how spoilt we are on python that we can test
out 10 lines at a time.

	At least you didn't do what some girl did at my college... The
compiler listing got posted outside the computer room as a record for
compiler errors...

	She'd fed the OBJECT file to the COBOL compiler as the source.

In your subject line you state that you are an intermediate Python user. 
  These are not the errors an intermediate user would make, nor the 
questions an intermediate user would ask.  These are the errors that 
somebody who doesn't know Python would make.

Please do not misrepresent yourself.

~Ethan~

P.S.  The scale I am accustomed to is Novice -> Intermediate -> Advanced 
-> Master

Are there scales out there that would put these types of questions in 
the "intermediate" category?
