single # PyFilesystem2 Python's Filesystem abstraction layer. [PyPI version] [PyPI] [Downloads] [Build Status] [Windows Build Status] [Coverage Status] [Codacy Badge] [Docs] ## Documentation - [Wiki] - [API Documentation] - [GitHub Repository] - [Blog] ## Introduction Think of PyFilesystem's `FS` objects as the next logical step to Python's `file` objects. In the same way that file objects abstract a single file, FS objects abstract an entire filesystem. Let's look at a simple piece of code as an example. The following function uses the PyFilesystem API to count the number of non-blank lines of Python code in a directory. It works _recursively_, so it will find `.py` files in all sub-directories. ```python def count_python_loc(fs): """Count non-blank lines of Python code.""" count = 0 for path in fs.walk.files(filter=['*.py']): with fs.open(path) as python_file: count += sum(1 for line in python_file if line.strip()) return count ``` We can call `count_python_loc` as follows: ```python from fs import open_fs projects_fs = open_fs('~/projects') print(count_python_loc(projects_fs)) ``` The line `project_fs = open_fs('~/projects')` opens an FS object that maps to the `projects` directory in your home folder. That object is used by `count_python_loc` when counting lines of code. To count the lines of Python code in a _zip file_, we can make the following change: ```python projects_fs = open_fs('zip://projects.zip') ``` Or to count the Python lines on an FTP server: ```python projects_fs = open_fs('ftp://ftp.example.org/projects') ``` No changes to `count_python_loc` are necessary, because PyFileystem provides a simple consistent interface to anything that resembles a collection of files and directories. Essentially, it allows you to write code that is independent of where and how the files are physically stored. Contrast that with a version that purely uses the standard library: ```python def count_py_loc(path): count = 0 for root, dirs, files in os.walk(path): for name in files: if name.endswith('.py'): with open(os.path.join(root, name), 'rt') as python_file: count += sum(1 for line in python_file if line.strip()) return count ``` This version is similar to the PyFilesystem code above, but would only work with the OS filesystem. Any other filesystem would require an entirely different API, and you would likely have to re-implement the directory walking functionality of `os.walk`. ## Credits The following developers have contributed code and their time to this projects: - [Will McGugan] - [Martin Larralde] - [Giampaolo Cimino] - [Geoff Jukes]
