Path Handling (pathlib)¶

Python provides the pathlib module for working with file system paths.

It offers a modern and object-oriented interface for path manipulation.

## 1. Creating Paths

```python
from pathlib import Path

p = Path("data.txt")

2. Checking File Existence¶

p.exists()
p.is_file()
p.is_dir()

3. Joining Paths¶

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

This avoids manual string concatenation.

4. Reading and Writing¶

p = Path("hello.txt")

p.write_text("Hello")
print(p.read_text())

5. Iterating Through Directories¶

p = Path("data")

for item in p.iterdir():
    print(item)

6. Advantages of pathlib¶

clearer code
platform independence
easier path manipulation

7. Summary¶

Key ideas:

pathlib.Path represents filesystem paths
paths can be joined using /
methods support reading, writing, and inspection
pathlib simplifies file system interactions
