Port existing project from TypeScript to Python

This is the project: [login to view URL] It's currently written in TypeScript. The port should be made to work for Python 3.6+ (can also be 3.7) preferably with type annotations. While the same file structure should be kept, the naming convention should be python's of course. The porting should be done mostly 1 to 1 since it doesn't use any other packages, except nomnom (argparse). The project has (including whitespaces) 590 lines.
