(OOP) Operating system paths and files.
Let Python operating system paths and files become Simple, Simpler, Simplest, Humanization, Unification, Flawless.
pip3 install systempath
>>> from systempath import SystemPath, Directory, File
>>> root = SystemPath('/')
>>> home: Directory = root['home']['gqylpy']
>>> home
/home/gqylpy
>>> file: File = home['alpha.txt']
>>> file
/home/gqylpy/alpha.txt
>>> file.open.rb().read()

篡改属性 __dict__ 以避免在外部修改其子类实例的属性，但严重的问题是篡改后无法反序列化其子类实例。
例如增加一个名为 Content.find 的方法，可查找文件中的内容。
移动或重命名文件有多个内置函数可选: os.rename() os.renames() shutil.move() 等。它们有何区别，以及哪个更适合我们。
异常类 SystemPathNotFoundError 存于内部模块，无法被外部直接导入，无法仅处理它的异常。当引发它时只能通过例如 except Exception 的方式处理，过于宽泛。
对于重命名文件或目录的操作，若目标路径是相对的且没有任何上级路径，我们将以原路径的上一级路径作为目标路径的父路径，而非常规的以当前工作目录。我们经历过大量的实践，以及在分析了大量的案例后得出的结论：
当目标路径是相对的且没有任何上级路径时，目标路径几乎 “追随” 原路径的上一级路径。
