类似字节的对象是必需的，而不是＆＃39; str＆＃39;

Question

import socket

IP = "127.0.0.1"
PORT = 5200

# Create a TCP/IP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# Connecting to remote computer 80
server_address = (IP,PORT)
sock.connect(server_address)
# Sending data to server


x = input('enter firstname:')
sock.send(x)
y = input("enter lastname:")
sock.send(y)

server_msg = sock.recv(1024)
print (server_msg)


# Closing the socket
sock.close()

当我运行代码时，我收到此错误＆＃34;类似字节的对象是必需的，而不是＆＃39; str＆＃39; ＆＃34; ，任何想法如何解决？ 当我输入名字时，我收到此错误。

Answer 1

input()返回一个字符串，但send()需要字节。您需要对字符串进行编码：

x = input('enter firstname:')
sock.send(x.encode("utf-8"))
y = input("enter lastname:")
sock.send(y.encode("utf-8"))

Answer 2

这里是代码（确保你已经安装了sockData模块）：

model.null_deviance 
model.deviance
