程序忽略if语句（MD5检查器）

Question

我对编程还比较陌生，刚开始工作。我被要求提出两份申请。一种获取和存储文件信息的方法，如文件名、大小、上次修改时间和MD5校验和，然后为多个文件编写一个包含该数据的文件；这个程序运行得很好

我的第二个程序（我将在下面为其发布代码）应该检查创建的文件，并将其与文件的当前条件进行比较。如果MD5 sum随其他属性一起更改，那么程序不会给出警告。但是，如果所有属性都保持不变，但是MD5发生了更改，那么程序会发出警告，因为出现了问题

我遇到的问题是如何让checker程序正常工作。我是一个初学者，所以如果有人能看看我的代码，看看我哪里出了差错，我会很感激的

这是我产生的代码

 files = glob('C:\pytesty\*\*')


filecheck = open('MD5report.dat', 'r')
for fil3 in files:
          fil3md5 = open(fil3, 'rb')
          md5read = fil3md5.read()
          hashy = hashlib.md5(md5read).hexdigest()
          filsize = os.path.getsize(fil3)
          filtime = time.ctime(os.path.getmtime(fil3))
          fline = filecheck.readline()
          [finame, fiMD5, fiSize, fidate, eofline] = fline.split('|')
          print (hashy + fiMD5)

          if (finame == fil3 and fiSize == filsize and fidate == filtime and fiMD5 != hashy):
                    print(finame + ': Wrong md5')
          else:
                    print(finame + ': is OK')

“MD5report”文件的内容如下：

当我运行程序时，我得到：

>>> 

如您所见，程序认为所有文件都是“正常”的，尽管它们不是，因为我故意更改了报告文件中的第一个MD5校验和

我试图寻找一些解决方案，但它们要么与这个特定场景无关，要么根本不起作用

如果能帮上点忙，我将不胜感激

Answer 1

如果满足所有其他条件，代码只打印哈希不匹配的内容。因此，如果由于某种原因，文件名、日期或大小不相同，if将永远不会执行表示哈希错误的代码。它将直接转到表示文件正常的行

我建议分别检查这些条件，以确保显示正确的错误消息
