Modules - pathlib

introduced in Python 3.4, and it provides an object-oriented way to work with filesystem paths

High-level Path objects instead of string-based path manipulation
Cross-platform path handling (Windows vs Unix differences handled automatically)
Easy file operations: reading, writing, iterating, checking existence
Cleaner, more expressive code than os.path

from pathlib import Path 

p = Path("data/example.txt") 

# Check existence 
print(p.exists()) 

# Read text 
content = p.read_text() 

# Write text 
p.write_text("Hello, world!")
