path 16.10.2

A module wrapper for os.path

path (aka path pie, formerly path.py) implements path objects as first-class entities, allowing common operations on files to be invoked on those path objects directly. For example:

from path import Path

d = Path("/home/guido/bin")
for f in d.files("*.py"):
    f.chmod(0o755)

# Globbing
for f in d.files("*.py"):
    f.chmod("u+rwx")

# Changing the working directory:
with Path("somewhere"):
    # cwd in now `somewhere`
    ...

# Concatenate paths with /
foo_txt = Path("bar") / "foo.txt"

Path pie is hosted at Github.

Advantages

Path pie provides a superior experience to similar offerings.

Python 3.4 introduced pathlib, which shares many characteristics with path. In particular, it provides an object encapsulation for representing filesystem paths. One may have imagined pathlib would supersede path.

But the implementation and the usage quickly diverge, and path has several advantages over pathlib:

• path implements Path objects as a subclass of str, and as a result these Path objects may be passed directly to other APIs that expect simple text representations of paths, whereas with pathlib, one must first cast values to strings before passing them to APIs that do not honor PEP 519 PathLike interface.

• path give quality of life features beyond exposing basic functionality of a path. path provides methods like rmtree (from shlib) and remove_p (remove a file if it exists), properties like .permissions, and sophisticated walk, TempDir, and chmod behaviors.

• As a PyPI-hosted package, path is free to iterate faster than a stdlib package. Contributions are welcome and encouraged.

• path provides superior portability using a uniform abstraction over its single Path object, freeing the implementer to subclass it readily. One cannot subclass a pathlib.Path to add functionality, but must subclass Path, PosixPath, and WindowsPath, even to do something as simple as to add a __dict__ to the subclass instances. path instead allows the Path.module object to be overridden by subclasses, defaulting to the os.path. Even advanced uses of path.Path that subclass the model do not need to be concerned with OS-specific nuances. path.Path objects are inherently “pure”, not requiring the author to distinguish between pure and non-pure variants.

This path project has the explicit aim to provide compatibility with pathlib objects where possible, such that a path.Path object is a drop-in replacement for pathlib.Path* objects. This project welcomes contributions to improve that compatibility where it’s lacking.

Origins

The path.py project was initially released in 2003 by Jason Orendorff and has been continuously developed and supported by several maintainers over the years.
