Python 绑定套接字时出错

我正在编写一个服务器脚本，用于很多事情，如游戏、数据传输、聊天等

我的问题是我遇到了以下错误：

Traceback (most recent call last):
File "server.py", line 11, in <module>
s.bind((host, port))
File "/usr/lib/python2.7/socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
TypeError: an integer is required

端口应为整型。将线路端口='5002'更改为端口=5002哦，天哪，我怎么会错过它，我不敢相信自己。非常感谢你！

#!/usr/bin/python

# This is server file

import socket

# server & connection settings
host = '127.0.0.1'      
port = '5002'
s = socket.socket() # Creating socket object
s.bind((host, port))
s.listen(10)
# server & connection settings

while True:
    c,addr = s.accept()                         # Establish connection with clients.
    print 'Got connection from ', addr                  # Print ip adress of the recently connected client.
    c.send('You succesfully established connection with our servers.')  # Send socket to the client.
    print 'Socket had been sent to the client: ', addr          # Print to the server console that we succesfully established connection with the client
    c.close()                               # Close the client connection. Bye, bye! /// Will delete this part when the time come
