Python + request get a response (elapsed) and response time (timeout) "Seven"

When requests issued request, the response time of the interface, a point is we need to focus, if the response time is too long, it is unreasonable.
If the server did not respond in a timely manner, we can not have been waiting for, you can set a timeout timeout

Specific implementation is as follows:

　　Timeout (default unit: s):

      　　timeout = 0.5: to set the timeout time of less than 0.5s

            timeout = (0.5,0.8): Wait Time Setting Section

　　　　When a timeout occurs, it will throw this exception: requests.exceptions.ConnectTimeout: HTTPConnectionPool　　　　

　　Gets Response time:

　　　   r.elapsed.total_seconds()  

　　　　   

#-*- coding:utf-8 -*-
import requests
from requests import exceptions

try:
    #timeout=0.1 ，timeout=(0.5,0.8)
    r = requests.post(url=url, data=data, headers=headers, verify=False, timeout=0.5)

　　 r.elapsed.total_seconds() #获取实际的响应时间 

　　 print r.json()

the except exceptions.Timeout AS E: 

　　Print ( "thrown")
