if __name__ == "__main__":确认脚本是在主程序中运行; file_path = 'your_file_path_here':替换为你的文件路径; print(f"The SHA-256 hash of the file is: {hash_value}"):打印出文件的 SHA-256 哈希值。 代码整体示例 下面是将所有片段整合在一起的完整示例: importhashlibdefcalculate_file_h...
I'm using this code to calculate hash value for a file: m = hashlib.md5() with open("calculator.pdf", 'rb') as fh: while True: data = fh.read(8192) if not data: break m.update(data) hash_value = m.hexdigest() print hash_value when I tried it on a folder "...

2. Python中的内置Hash函数Python内置了一个hash()函数，用于计算对象的哈希值。不同类型的对象（如整数、字符串、元组等）具有不同的哈希函数实现。# 使用hash()函数计算哈希值hash_value1 = hash(42)hash_value2 = hash("Hello, Python!")hash_value3 = hash((1, 2, 3))print(f"Hash value of 42:...
每次向字典或集合插入一个元素时,Python会首先计算键的哈希值(hash(key)),再和 mask = PyDicMinSize - 1做与操作,计算这个元素应该插入哈希表的位置index = hash(key) & mask。如果哈希表中此位置是空的,那么这个元素就会被插入其中。 而如果此位置已被占用,Python便会比较两个元素的哈希值和键是否相等。 若...
