Defining constant strings

Sun Aug 27 12:53:02 EDT 2006

I would really like to highlight something Tal has already said: Python
strings are immutable. That means if you construct a string object, you
don't have to worry about someone else going in and changing that
object. What might happen, however, is that someone might reassign a
variable you have which points to that object. You can tell people not
to do this (although you can't force them) using a mechanism Tal has
also described. You give your variable a name which is all caps.
