Well *now* we're talking semantics, or at least terminology.

Perhaps I misinterpreted the original poster's use of the 
word "extension".  He said he was "brand new to Python" and 
I therefore assumed he was not attempting already to install 
an "extension" (per your usage of the term) but instead a module 
or package.  If I was wrong about that, then forgive me for 
confusing the issue.

Meanwhile, is it really the case that "extension" refers 
exclusively to code not written in Python?  If so, please
refer me to where the official definition has been made
so I can set my mind at ease.

(But even then I would argue that the term extension should
refer to a module, package, or set of code, whether written
in Python or not, which is intended to be installed in such a 
way that it becomes available to all Python programs on a 
system, in the way the standard library is.  That, at least,
seems the definition likely to fulfill the "least astonishment"
principle...)
