问题描述
我是 python 编程的新手,我有点困惑.我尝试从字符串中获取字节以进行散列和加密,但我得到了
I am new in python programming and i am a bit confused. I try to get the bytes from a string to hash and encrypt but i got
b'...'
b 字符串前面的字符,如下例所示.有什么办法可以避免这种情况吗?谁能给出解决方案?对不起这个愚蠢的问题
b character in front of string just like the below example. Is any way avoid this?.Can anyone give a solution? Sorry for this silly question
import hashlib text = "my secret data" pw_bytes = text.encode('utf-8') print('print',pw_bytes) m = hashlib.md5() m.update(pw_bytes)
输出:
print b'my secret data'
推荐答案
解码是多余的
你一开始只有这个错误",因为对正在发生的事情有误解.
You only had this "error" in the first place, because of a misunderstanding of what's happening.
您获得了 b,因为您编码为 utf-8,现在它是一个字节对象.
You get the b because you encoded to utf-8 and now it's a bytes object.
>> type("text".encode("utf-8")) >> <class 'bytes'>
修复:
- 你可以先打印字符串
- 编码后冗余解码
