Path Module

The path module provides filesystem path manipulation and querying functions. These functions operate on path strings — they do NOT modify the filesystem.

Import

import path

API Reference

Queries

Function	Returns	Description
exists(p)	bool	Check if path exists
is_file(p)	bool	Check if path is a regular file
is_dir(p)	bool	Check if path is a directory
is_abs(p)	bool	Check if path is absolute
size(p)	int	File size in bytes, -1 on error

Manipulation

Function	Returns	Description
basename(p)	str	Last component: "/a/b.txt" → "b.txt"
dirname(p)	str	Parent directory: "/a/b.txt" → "/a"
ext(p)	str	File extension: "file.txt" → ".txt"
stem(p)	str	Name without extension: "file.txt" → "file"
join(a, b)	str	Join path components
abs(p)	str	Resolve to absolute path
clean(p)	str	Normalize ., .., duplicate /

Usage Example

import path

def main() -> int:
    let file = path.join("/home/user", "data.csv")
    print(f"File: {file}")
    print(f"Dir:  {path.dirname(file)}")
    print(f"Name: {path.basename(file)}")
    print(f"Ext:  {path.ext(file)}")

    if path.exists(file):
        print(f"Size: {path.size(file)} bytes")
    0
