This file exports a standardized set of tools for working with files. The library offers at least some portability across the file systems used in the three supported platforms: Mac OSX, Windows, and Linux. Directory and search paths are allowed to contain separators in any of the supported styles, which usually makes it possible to use the same code on different platforms.

Note: Several of the functions that lived in CPP’s version of this library are removed, to force students to learn the proper builtin pathlib library. The compatability is listed here:

def create_directory(path):

def create_directory_path(path):
    _Path(path).mkdir(path, parents=True)

def default_extension(path, ext):
    p = _Path(path)
    if ext.startswith('*') or not p.suffix:
        return p.with_suffix(ext)

def delete_file(path):
    return os.remove(path)
