develop small PYTHON based macro language with portable runtime

I need an small commandline tool that can start scripts in his own macro language like an testing tool The tool used files that can write by an normal editor(can be Notepad++ or an easy notepad with syntax highlighting) The tool has an runtime so it can start without any editor. It runs step by step through the script and is running the macros. Here a explanation sample: 1. CONFIG(Outputfile) 2. WAIT(10 s) 3. MESSAGE(Ask the user something - with UI) 4. WRITE(answer to the file) scripts can start with: [login to view URL] [login to view URL] Option to have an Debugger for testing the scripts would be nice. The tool has an easy to expand standard macro list file that has different macro commands(functions) in. This should be expandable by my own with python functions(macros). The runtime tool needs to run on windows PC without installing(portable) and is using PYVISA library. I need a first set of following functions(macros) to develop my own scripts. So building the first set of macros and writing the first script is part of the project. Here the macros I need: CONFIG() MEAS() MESSAGE() RESULT() TALK() WAIT() ACC() COMPARE() What they should do(methods and parameter) you can see in the attached PDF in an small example. I´m sure that this project can good solved in PYTHON. The delivery needs a description how an own function(macro) can attach and all inserted functions has an small in code description with there methods or parameter. The description should readable by an documenting tool. Keep in mind it should be an portable windows tool at the end.
