Microsoft Visual C++ Compiler for Python 3.4
Unfortunately to be able to use the extension modules provided by others you'll be forced to use the official compiler to compile Python. These are:
Visual Studio 2008 for Python 2.7.See: https://docs.python.org/2.7/using/windows.html#compiling-python-on-windows
Visual Studio 2010 for Python 3.4.See: https://docs.python.org/3.4/using/windows.html#compiling-python-on-windows
Alternatively, you can use MinGw to compile extensions in a way that won't depend on others.
See: https://docs.python.org/2/install/#gnu-c-cygwin-MinGW or https://docs.python.org/3.4/install/#gnu-c-cygwin-mingw
This allows you to have one compiler to build your extensions for both versions of Python, Python 2.x and Python 3.x.
For the different python versions:
Visual C++ |CPython--------------------14.0 |3.510.0 |3.3, 3.49.0 |2.6, 2.7, 3.0, 3.1, 3.2Source: Windows Compilers for py

Visual Studio Community 2015 suffices to build extensions for Python 3.5. It's free but a 6 GB download (overkill). On my computer it installed vcvarsall at C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat
For Python 3.4 you'd need Visual Studio 2010. I don't think there's any free edition. See https://matthew-brett.github.io/pydagogue/python_msvc.html
