Step by Step compiler for python?

I think you're looking for something like Jupyter Lab or Jupyter Notebook.
You can even try it out in your browser: https://jupyter.org/

There is http://pythontutor.com/ ( github ) but it's only meant for snippets of code.
For full applications you'll likely want the best debugger you can find.

Might looking something like udemy.com?

Microsoft Visual Studio with the appropriate python components installed should work too.

Thank you guys for showing me the potential of some applications like Pycharm and the pythontutor website. You guys have been very helpful, thank you!
