This is a simple Cython example I made from another website's tutorial. I remember when I was trying to extend Python functionality with C. It wasn't too bad, but Cython makes it a lot easier. Here are the files for the example.
1. Install Cython: “pip install cython” from windows command line.
2. Download and install Visual C++ Compiler for Python 2.7 (https://www.microsoft.com/en-us/download/details.aspx?id=44266)
3. Open the “Visual C++ 2008 64-bit Cross Tools Command Prompt”
4. Go to the directory where “fib.pyx” and “setup.py” exist.
5. Type in “fib.bat”
6. Run the “testfib.py”
