I have a class named SSLXMLRPCServer. Should it be that or SslXmlRpcServer?
The problem with uppercase acronyms in CamelCase names is that the word following the acronym looks like a part of it, since it begins with a capital letter. Also, when you have several in a row as in your example, it is not clear where each begins. For this reason, I would probably use your second choice.
If my python class name has an acronym, should I keep it upper case, or only the first letter?
