在Python中对IP地址进行多线程ping

Question

我有一个IP地址列表，比如1000个no。我正在阅读ip_file.txt并将结果文件存储为result_date.txt。下面是我实现结果的代码。但我的问题是执行整个文件花费的时间太长了。有人可以建议多线程，请这样可以快速实现预期的结果?提前谢谢。

#!/usr/bin/env python
import os
import csv
import paramiko
from datetime import datetime
import time
import sys
import re
from collections import defaultdict
# Verifies your os type
from paramiko import file
OS_TYPE = os.name
# Sets the count modifier to the os type
count = '-n' if OS_TYPE == 'nt' else '-c'

def create_ip_list():
ip_list = []
with open("ip_file.txt", "r") as file:
for line in file:
ip_list.append(line.strip())
return ip_list
# fetching data
now = datetime.now()
dat = now.strftime("%d/%m/%Y")
# time = now.strftime("%H:%M:%S")
date_string = dat.replace('/', '-')
timestr = time.strftime("%d%m%Y-%H%M%S")

def ping_device(ip_list):
"""Ping ip_list and return results
return: None
rtype: None
"""
results_file = open("results_" + str(timestr) + ".txt", "w")
for ip in ip_list:
response = os.popen(f"ping {ip} {count} 1").read()
time.sleep(1.5)
#fetch Average time
print(response)
for i in response.split("n"):
para = i.split("=")
try:
if para[0].strip() == "Minimum":
latency = para[3].strip()
print(latency)
# output1=latency[0:8].split(" ")
# test=output1[0]
# print(test)
except:
print("time run")
if "Received = 1" and "Approximate" in response:
#print(f"UP {ip} Ping Successful")
results_file.write(f"{ip},UP,{latency}" + "n")
else:
print(f"Down {ip} Ping Unsuccessful")
results_file.write(f"{ip} Down" + "n")
results_file.close()
if __name__ == "__main__":
ping_device(create_ip_list())

Answer 1

编写一个函数ping_one_device，它接受单个ip并返回一个给出状态的字符串。从ping_device中取出这个应该很容易。

然后

with open(results_file, "w") as results_file:
with ThreadPoolExecutor() as executor:
for result in map(ping_one_device, ip_list):
results_file.write(result)
