How do you create constants?

[Steve Horne]

Adding the const concept to a language when that language is already
in widespread use is difficult to do well. Consider the problems that
occur in well written C++, when you reach a level where you are
calling into old C routines that don't have constant parameters tagged
as const - real typecast hell!

Python is at heart a scripting language, and IMNSHO doesn't need
paranoia constructs.
