我想把这个C#代码转换成Python。我想像C#代码那样用utf-8编码做SHA256散列。但是当我打印结果时，它们就不一样了（结果在注释行中）。我错过的重点是什么？

发件人:

    //C# code
    string passw = "value123value";
    SHA256CryptoServiceProvider sHA256 = new SHA256CryptoServiceProvider(); 
    byte[] array = new byte[32];
    byte[] sourceArray = sHA256.ComputeHash(Encoding.UTF8.GetBytes(passw));          
    Console.WriteLine(Encoding.UTF8.GetString(sourceArray)); //J�Q�XV�@�?VQ�mjGK���2

致:

    #python code
    passw = "value123value"
    passw = passw.encode('utf8') #convert unicode string to a byte string
    m = hashlib.sha256()
    m.update(passw)
    print(m.hexdigest()) #0c0a903c967a42750d4a9f51d958569f40ac3f5651816d6a474b1f88ef91ec32
