我正在尝试从 python 上的 os.system('ping') 函数确定 time/latency

Question

import os import time for i in range(20): start = time.time() os.system('ping -n 1 {}'.format('google.com')) end = time.time() 我尝试了这个，但最后 - 开始效率不高，所以我试图找到一个解决方案，了解如何从表扬中获得时间

Answer 1

试试这个：

 def TicTocGenerator():
        # Generator that returns time differences
        ti = 0  # initial time
        tf = time.time()  # final time
        while True:
            ti = tf
            tf = time.time()
            yield tf - ti  # returns the time difference


    TicToc = TicTocGenerator()  # create an instance of the TicTocGen generator

    def toc(tempBool=True):
        # Prints the time difference yielded by generator instance TicToc
        tempTimeInterval = next(TicToc)
        if tempBool:
            print("Elapsed time: %f seconds.\n" % tempTimeInterval)
    
    
    def tic():
        # Records a time in TicToc, marks the beginning of a time interval
        toc(False)
    
    
    
    
    tic()
    #your code here
    toc()

但如果您需要 ping 统计信息，您可以使用：

from pythonping import ping

PingRes = ping(target=self.ip,timeout=3,count=3, verbose=True)

我正在尝试从 python 上的 os.system('ping') 函数确定 time/latency

Am trying to determent the time/latency from os.system('ping') function on python

python

system
