关于python的hashlib md5的报错处理

1.报错信息是：TypeError: Unicode-objects must be encoded before hashing

2.报错信息是：TypeError: object supporting the buffer API required

正确的写法应该是

代码：

import hashlib
def md5pwd(password):
m = hashlib.md5()
m.update(password)
mpwd = m.hexdigest()
return mpwd
print(md5pwd(b'123456'))
