Why? Python has an infinite number of constants. The only difference is 
that they are immutable objects, not names.

But regardless... yes, it is in my opinion Pythonic to use ALLCAPS to 
designate constants (by convention). It isn't in PEP 8, but I don't think 
that matters unless PEP 8 suggests a different convention.
