The tools below are built using a popular programming language called Python, which is both easy to learn and run. You can download the Python script file for each tool from the Engineering Your FI GitHub page. 

September 2022 update: I’ve now placed an embedded Python interpreter in many of the posts corresponding to these tools, which means you can edit the inputs and/or code and then run directly from the post! See the “Code” section in each post, which you can access easily via the Table of Contents at the top.

One day I may create nice graphical interfaces for these tools, but for now I’ve made it as easy as possible to modify and run these Python scripts. All user inputs are in a distinct “Inputs” section at the top, so all you have to do is tweak those to your liking and hit run.

If you’d like to install and run Python on your computer, you can download it and follow any number of great instructions available. I also recommend downloading and installing PyCharm (my favorite) or VS Code, which are programs that make it easier to edit and run your code.

If you’d rather not deal with installing Python and you’re not a fan of the Python interpreter I’ve placed in each post, you can also use one of the many other online interpreters (though I have not tested my scripts on these): Repl.it, Tutorialspoint, Geekflare, Programiz, Python.org, OneCompiler, OnlineGDB, PYnative, CoCalc, Online Python.
