Ping 的 Python 控制台和文本输出，包括

Python console and text output from Ping including (Ping 的 Python 控制台和文本输出，包括 )

问题描述

我不知道发生了什么，但是当我打印到控制台或文本文件时，换行符 ( ) 不起作用，而是显示在字符串中.知道如何在控制台和文本文件中避免这种情况吗?

I dont know what is happening, but when I am printing to the console or to a text file, the newline ( ) is not functioning but rather showing in the string. Any idea how to avoid this in both the console and the text file?

我的代码:

import subprocess

hosts_file = open("hosts.txt","r")
lines = hosts_file.readlines()

for line in lines:
    line = line.strip()
    ping = subprocess.Popen(["ping", "-n", "3",line],stdout = subprocess.PIPE,stderr = subprocess.PIPE)
    out, error = ping.communicate()
    out = out.strip()
    error = error.strip()
    output = open("PingResults.txt",'a')
    output.write(str(out))
    output.write(str(error))
    print(out)
    print(error)
hosts_file.close()

输出:

推荐答案

import subprocess

hosts_file = open("hosts.txt","r")
lines = hosts_file.readlines()
hosts_file.close()

for line in lines:
    ping = subprocess.Popen(["ping", "-n", "3",line.strip()], stdout=subprocess.PIPE, stderr=subprocess.POPEN)
    with open('PingResults.txt', 'ab') as fh:
        for line in ping.stdout.readlines():
            fh.write(line)
    ping.stdout.close()

给我:

[torxed@faparch ~]$ python test.py && cat PingResults.txt
