Python &引用；“哈希校验和”；对象支持所需的缓冲区API

我试图计算pycharm中“Disk image”USbImg.E01的散列值

import hashlib

try:
    file = open("F:/USB Try MATCH/USBTRY.E01",'r')
except:
    print("\nFile not found")
ad5 = hashlib.md5()
ad5.update(file)
print("md5: %s" % ad5.hexdigest())

对象支持所需的缓冲区API

---

请尝试

ad5.update（file.read（））

请在回答中添加解释

import hashlib
fiename = 'F:/NEWIMG2/ABC.E01'
hashermd5 = hashlib.md5()
with open(fiename,'rb') as open_file:
    content = open_file.read()
    hashermd5.update(content)
print("md5: %s" % hashermd5.hexdigest())
