Python批量校验两个文件夹里面的文件MD5

import base64
import hashlib
import os
g_origin_path = "【目录】"
g_target_path = "【目录】"


def get_file_md5(filepath):
    f = open(filepath, 'rb')
    md5obj = hashlib.md5()
    md5obj.update(f.read())
    hash = md5obj.hexdigest()
    f.close()
    return str(hash).upper()


for root, dirs, files in os.walk(g_origin_path):
    for file in files:
        origin_file_path = os.path.join(root, file)
        strlist = origin_file_path.split('\\')
        target_file_path = g_origin_path + '\\'.join(strlist[5:])
        if os.path.exists(target_file_path) == False:
            print("多出文件: {} ".format(target_file_path))
            continue
        origin_file_md5 = get_file_md5(origin_file_path)
        target_file_md5 = get_file_md5(target_file_path)

        #print(origin_file_md5, target_file_md5)
        if origin_file_md5 != target_file_md5:
            print("md5不同 路径: {} src: {} target: {}".format(
                target_file_path, origin_file_md5, target_file_md5))

网上的东西都不怎么靠谱，用来快速确认有没有后门之类的东西
