python实现基于Socket的客户端与服务器的对讲通信

server端为
import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('127.0.0.1', 9090))
s.listen(5)
print 'serve is waiting connect...'

while True:
sock, addr = s.accept()
data = sock.recv(1024)
print(data)
socket.send('Hello, I am server.')

client端为
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1', 9090))

while True:
s.send(bytes('Hello, I am client'))
data = s.recv(1024)
print(data)
为什么运行出不来，该修改哪里？
>>> python server.py
File "<stdin>", line 1
python server.py
^
SyntaxError: invalid syntax
>>> python client.py
File "<stdin>", line 1
python client.py
^
SyntaxError: invalid syntax

使用多线程，下面的代码，简单实现一个多线程的web服务器：

#coding=utf-8
import socket
import threading
from time import sleep
def response(sock, addr):
    print "收到请求"
    data = sock.recv(1024)
    print data
    sock.send(html)
    sock.close()
html = '''HTTP/1.1 200 OK\nContent-Type: text/html\n\r\nHello world!'''
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('0.0.0.0', 80))
s.listen(50)
print "正在等待连接……"
while 1:
    sleep(0.1)
    sock,addr = s.accept()
    t = threading.Thread(target=response, args=(sock,addr))
    t.start()
