python 使用hashlib计算文件的（md5）哈希值

Posted 2021-05-09

import hashlib

def calc_hash(file_path, hash_type=hashlib.md5(), block_size=2 ** 20 * 60):
    m = hash_type
    with open(file_path, 'rb') as f:
        chunk = 0
        while chunk != b'':
            chunk = f.read(block_size)
            m.update(chunk)

    return m.hexdigest()
