[54] Python 3.0 was released on 3 December 2008, with some new semantics and changed syntax.

Microsoft has published naming conventions for identifiers in C#, which recommends the use of PascalCase for the names of types and most type members, and camelCase for variables and for private or internal fields. [1]
In computer programming, a fully qualified name is an unambiguous name that specifies which object, function, or variable a call refers to without regard to the context of the call. [ citation needed ] In a hierarchical structure , a name is fully qualified when it "is complete in the sense that it includes (a) all names in the hierarchic ...
