错误处理python

-1

试图做一个简单的错误处理，看看主机是否无法访问，我一直得到一个无效的语法except。错误处理python

import socket    

s = socket.socket()   
host = "" 
port = 1337    

print(""" 
============================================ 
Welcome to Coder77's local internet messager 
============================================ 
The current soon to be encrypted server is {0} 
""".format(host)) 

host = input("Please select the IP you would like to communicate to: ") 
print("Now connecting to {0}....".format(host)) 

try: 
     s.connect((host, port) 
except socket.error as s: 
     print ("Host is unreachable") 


print (s.recv(2048)) 
input("Close") 
s.close()

规则：每当你得到一个奇怪的语法错误，看看在*之前*网上看到如果括号，括号和括号是平衡的。 –

s.connect((host, port)

应该是拇指

s.connect((host, port))

变化s.connect((host, port)到s.connect(host, port)

不，它应该是's.connect（（主机，端口））'。 ['socket.connect（）']（http://docs.python.org/2/library/socket.html#socket.socket.connect）只需*一个*参数。 –
