Re: [Py2exe-users] Re: looking for some info re: virus removals - C++ versus Py

[Voidspace <mi...@pc...>]

Just to confirm.
py2exe will generate *all* the files needed by your scripts - you will
have no external dependicies other than the files produced by py2exe
(which includes the necessary python dll).

There are various different libraries that will do all that you need
(from my understanding anyway).
You'll find the learning curve for python very quick - although there
are a few minor pitfalls along the way !!
