如何用os.system在Python中进行简单的ping并将结果保存到文件中

Question

我写了一个简单的Python脚本：

import os
os.system("ping www.google.com")

这个脚本在Windows的命令行中可以正常运行，但在IDLE中运行时却出现了一个黑色的命令行窗口，这就是我遇到的第一个问题。

我还想做的第二件事是：我想把ping的结果保存到一个文件里。请问我该怎么做呢？

我刚学Python（才两天）；）非常感谢！

你可以用 subprocess.check_output 来保存输出结果。

    import subprocess
    with open('output.txt','w') as out:
        out.write(subprocess.check_output("ping www.google.com"))

output.txt
