Python套接字程序

Question

我正在尝试用Python编写一个socket程序。在我的客户端，我有以下部分：

clientSocket = socket(AF_INET, SOCK_STREAM)         
clientSocket.connect((serverName, serverPort))

linesInBytes = clientSocket.recv(1024)
print(linesInBytes) 

在服务器端，我有：

connectionSocket, addr = serverSocket.accept()
#Set secret word
word = 'Arkansas'
linesForString = ''     
#Prints out number of letters
for x in word:
    linesForString += '_ '

linesInBytes = linesForString.encode('utf-8')
connectionSocket.send(linesInBytes)

出于某种原因，当它在客户端打印出来时，它会打印出：

b’’\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu’

在代码里没有我打印出b的地方。这个b是从哪里来的？？ 谢谢您！你知道吗

Answer 1

.decode('utf8')将接收到的数据字节还原为字符串。python3显示b''来表示字节字符串与Unicode字符串。你知道吗
