How to Compare Two Files by Content Hash Equality in Python

Compares two files by hashing their contents with SHA-256, skipping the hash if file sizes differ, and returns whether they are identical.

hashlib sha256 file-hashing

Python

import hashlib
from pathlib import Path

def file_hash(path: Path, chunk_size: int = 8192) -> str:
    sha256 = hashlib.sha256()
    with path.open("rb") as f:
        for chunk in iter(lambda: f.read(chunk_size), b""):
            sha256.update(chunk)
    return sha256.hexdigest()
