Реализация ping с использованием Python

Question

Я пытаюсь выполнить ping ряд серверов, и я хочу сохранить вывод ping. Это все, что у меня есть.

import subprocess 

string_part = 'ping -W 2 -c 2 64.233.' 

for i in range(160,165):    
    for j in range(0,5): 
      prompt = string_part + str(i) + '.' + str(j) 
      result = subprocess.call(prompt, shell = True)  

Я думал, что если я дам «печать (результат)», после этого он напечатает результат. Однако он возвращает только 1. Я не хочу использовать потоки на данный момент. Кажется, я что-то упускаю! . :(

Answer 1

subprocess.call() возвращает код выхода процесса Чтобы получить на выходе стандартный вывод команды ping, используйте pipe и Popen.communicate() вместо:

string_part = 'ping -W 2 -c 2 64.233.{}.{}' 

for i in range(160, 165):    
    for j in range(5): 
      prompt = string_part.format(i, j) 
      proc = subprocess.Popen(prompt, shell=True, stdout=subprocess.PIPE) 
      result, _ = proc.communicate() 

Вы можете и должны избегать использования оболочку, просто передайте аргументы в списке:

command = ['ping', '-W', '2', '-c', '2'] 
ip_template = '64.233.{}.{}' 

for i in range(160, 165):    
    for j in range(5): 
      ip_address = ip_template.format(i, j) 
      proc = subprocess.Popen(command + [ip_address], stdout=subprocess.PIPE) 
      result, _ = proc.communicate() 

Answer 2

import subprocess 

string_part = 'ping -W 2 -c 2 64.233.' 
result=[] 
for i in range(160,165):    
    for j in range(0,5): 
      prompt = string_part + str(i) + '.' + str(j) 
      result.append(subprocess.call(prompt, shell = True)) 
print result 

Answer 3

Просто выходной магазин в Словаре с IP в качестве ключа и Popen.communicate[0] в качестве значения

string_part = 'ping -W 2 -c 2 64.233.{}.{}' 
d = {} 

for i in range(160, 165): 
    for j in range(0, 5): 
     prompt = string_part.format(i,j).split() 
     proc = subprocess.Popen(prompt, stdout=subprocess.PIPE, stderr=subprocess.PIPE) 
     d[prompt[-1]] = proc.communicate()[0] 
print d
