Probably a little advanced for this list but the list is here to learn
right? So my own 2 pence worth...

Are you referring to Python Tools for Visual Studio?
http://pytools.codeplex.com/

This allows you to build python projects in VS and then debug them using
the VS debugger, but you will need the debug files (.pdb) available on this
page: https://www.python.org/downloads/windows/ - This however is more for
extending python via C/C++ than building python apps or using python to
deploy apps.

There are a number of tools out there, some already mentioned for bundling
python apps into exe's which then require the python dlls to be packaged in
an installer to be deployed with your newly built exe. I have done this in
the past and experience has taught me one thing. Don't do it! You end up
making your app way too complex, and it becomes very difficult to support.
Also, when you want to update the python environment you run into problems.

infrastructure in place to make things easily repeatable, it still becomes
a nightmare.

Rather find an automated way of deploying python independently and then use
an installer to install just your python code. That way all you support is
your code, you don't end up supporting 3rd party wrappers that don't work
properly.

nullsoft scriptable installer is easy to use, has good documentation and
examples, and doesn't have a massively steep learning curve.
