[Tutor] exec versus execfile

[Stephan Richter]

Hello everyone,

I have a little Web application that will allow the user to type in some 
code which is then interpreted and the result (in this case an image - 
generated with PIL) will be returned.

Here my problem:
When I say: 'exec code' it gives me a syntax error. But if I save my code 
into a file and use 'execfile(filename)' everything works fine. This 
problem only occurs, if I have multiple lines in my code string. I noticed 
that the file uses '\015\012' to finish a line and my code string only uses 
'\012'. Is that a problem?
If I read the code I just saved to the file and try to exec it, the syntax 
error is thrown again.

I am really confused, why it is not working. I am using Python 1.5.2. Can 
someone shine some light on my situation?

Thanks in advance.

Regards,
Stephan
