初步实现检测文件查重的检测

适用于学校上机考试，查看是否有抄袭的现象。使用SHA-256算法计算文件的哈希值，并比较两个文件是否相同。

import hashlib

def calculate_file_hash(file_path, block_size=65536):
    sha256 = hashlib.sha256()
    with open(file_path, 'rb') as file:
        for block in iter(lambda: file.read(block_size), b''):
            sha256.update(block)
    return sha256.hexdigest()

def check_duplicate_files(file_path1, file_path2):
    hash1 = calculate_file_hash(file_path1)
    hash2 = calculate_file_hash(file_path2)

    if hash1 == hash2:
        print(f"The files {file_path1} and {file_path2} are duplicates.")
    else:
        print(f"The files {file_path1} and {file_path2} are not duplicates.")

# 示例用法
file_path_1 = 'path/to/file1.txt'
file_path_2 = 'path/to/file2.txt'

check_duplicate_files(file_path_1, file_path_2)
