Even though Python is an interpreted language, you may need to install Windows C++ compilers in some cases. Unlike Linux, compilers for Windows are not included by default in the OS.
For example, you will need to use them if you want to:
Install a non-pure Python package from sources with Pip (If there is no Wheel package provided).
Microsoft provides official C++ compilers called Visual C++, you can find them bundled with Visual Studio or, for some versions, in standalone distributions. Some alternative compilers exists like MinGW, but incompatibilities may occur with a CPython official distribution that is build with Microsoft Visual C++.
The compiler's architecture must be the same as Python's (for example: if you use Python 64bit, you have to use a x64 compiler).
Which Microsoft Visual C++ compiler use with a specified Python version ?
Each Python version uses a specific compiler version (e.g. CPython 2.7 uses Visual C++ 9.0, CPython 3.3 uses Visual C++ 10.0, ...). So, you need to install the compiler version that corresponds to your Python version :
Visual C++ |
CPython |
14.0 |
3.5 |
10.0 |
3.3, 3.4 |
9.0 |
2.6, 2.7, 3.0, 3.1, 3.2 |
Compilers Installation and configuration
Compatible architectures are specified for each compiler in brackets.

Install Microsoft Visual C++ Build Tools 2015. Check Windows 8.1 SDK and Windows 10 SDK options.
You have to run your commands from Visual C++ Build Tools Command Prompt (C:\Program Files (x86)\Microsoft Visual C++ Build Tools\) each time you want compile with Python.
If you want automatic use of this compiler with Python, you can also edit the C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat and replace its contents with the following text :
Microsoft Visual C++ 14.0 with Visual Studio 2015 (x86, x64, ARM)
Visual Studio 2015 contains Visual C++ 14.0 compiler. Distutils will automatically detect the compiler and use it.
