Hi,

In order to know the possible methods (functions) or attributes of an object (the data contained within that object), you should use the following Python command:

dir(object_name)

In your case, this would probably give:

dir(Bio.Alphabet.RNAAlphabet)

This will tell you what you can use or visualize in the object.

I suggest that you take some time familiarizing yourself with classes and object oriented programming in Python

EDIT:

Let's say the name of the attribute containing the data is 'letters', you can print it like this:

print Bio.Alphabet.RNAAlphabet.letters

If you don't want to print it, put it in a variable or torture it however you like :P.

Cheers
