The Path Object
Build paths the modern way.
The Path Object is a free Python Academy lesson on CoddyKit — lesson 1 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Python Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Modern Paths with pathlib
The pathlib module represents filesystem paths as objects instead of plain strings. A Path object knows how to join, split, and inspect itself, replacing many scattered os.path functions.
Creating a Path
Import Path and construct one from a string. Printing it shows the path text.
from pathlib import Path
p = Path('folder/file.txt')
print(p)Joining with the / Operator
The slash operator joins path parts. It is far more readable than string concatenation and handles separators correctly on every OS.
from pathlib import Path
base = Path('data')
full = base / 'reports' / 'march.txt'
print(full)Name, Stem, and Suffix
A path exposes its parts as properties: name is the final component, stem drops the extension, and suffix is the extension.
from pathlib import Path
p = Path('data/report.csv')
print(p.name)
print(p.stem)
print(p.suffix)Parent Directory
The parent property gives the containing directory as another Path. Chain it to climb upward.
from pathlib import Path
p = Path('a/b/c/file.txt')
print(p.parent)
print(p.parent.parent)All Parts
The parts property returns a tuple of every component, which is handy for iterating over a path's pieces.
from pathlib import Path
p = Path('usr/local/bin')
print(p.parts)Changing the Extension
with_suffix() returns a new path with a different extension, and with_name() replaces the whole final component.
from pathlib import Path
p = Path('report.txt')
print(p.with_suffix('.md'))
print(p.with_name('summary.txt'))Current and Home Directories
Class methods Path.cwd() and Path.home() give the current working directory and the user's home directory.
from pathlib import Path
print(type(Path.cwd()))
print(type(Path.home()))Checking Existence and Type
Query the filesystem with exists(), is_file(), and is_dir(). They return booleans without raising on a missing path.
from pathlib import Path
p = Path('definitely_not_here_12345.txt')
print(p.exists())
print(p.is_file())
print(p.is_dir())Paths Are Strings When Needed
Most file functions accept Path objects directly. When you truly need a string, wrap it in str().
from pathlib import Path
p = Path('data') / 'file.txt'
text = str(p)
print(text)
print(type(text))Cross-Platform by Design
A Path automatically uses the right separator for the operating system you run on. You write the same code with / joins, and it produces correct paths on Linux, macOS, and Windows.
from pathlib import Path
p = Path('config') / 'settings' / 'app.ini'
print(p)
print(p.name)Quick Check
What does the / operator do with Path objects?
Recap
You learned to build paths the modern way.
Pathrepresents a filesystem path as an object.- Join with
/; inspect withname,stem,suffix,parent,parts. with_suffixandwith_namederive new paths.- Check the filesystem with
exists,is_file,is_dir.
