Questions tagged [pathlib]

This tag is for questions about the Python built-in library pathlib, which offers classes representing filesystem paths with semantics appropriate for different operating systems.

This module offers classes representing filesystem paths with semantics appropriate for different operating systems. Path classes are divided between Pure paths, which provide purely computational operations without I/O, and Concrete paths, which inherit from pure paths but also provide I/O operations.

Its strength lies in that it offers a powerful Object Oriented interface for working with paths, as opposed to the string-based interface offered by os.path.

This table offers a mapping between various os functions to their corresponding PurePath/Path equivalent.

Python fails to execute code line by line and causes folder not found error by reading, writing, copying and deleting folders and csv files

I'm not sure how Python works internally to execute the code but I got a wired issue, which does not always happen but sometimes out of blue. I can even not locate the bug. In the frontend user clicks update button and the corresponding function is…

Python: os vs pathlib

What exactly are the advantages of os compared to pathlib ? To me pathlib seems nearly always the better choice, especially because most of the functionality of os can be reproduced by pathlib.os if I am not mistaken. So is the only advantage of os,…

Let's say I have a Path object like so: from pathlib import Path path = Path('/Users/Me/Desktop/Media/Pictures') On posix systems, this returns a PosixPath object, and on Windows, a WindowsPath object. Is there a nice, build-in Pythonic way to get…

Premise A convenient but fragile path might be written in Python as a string fdir = r'mydir/' fname = r'myfile' fpath = fdir + fname This is a terrible practice (np.inf demerits), but the syntax is concise and readable (+1 merits). Question Should…
