python - 如何将 IP 地址列表绘制为事件或非事件状态并保存到文本文件

Question

import subprocess
import os
import matplotlib.pyplot as plt
def Main ():
    ipaddress = open('ipaddress.txt', 'a')
    with open(os.devnull, "wb") as limbo:
        for n in range(1, 100):
            ip="192.168.1.{0}".format(n)
            result=subprocess.Popen(["ping", "-n", "1", "-w", "200", ip],
                stdout=limbo, stderr=limbo).wait()
            if result:
                print (ip + " inactive")
                ipaddress.write(ip + ' inactive')
            else:
                print (ip + " active")
                ipaddress.write(ip + ' Acive')
    ip = ip.split('\n')
    ip = [float(f) for f in ip]
    slice_labels = ['Active', 'Inactive']
    # Create a pie chart from the values.
    plt.pie(ip, labels=slice_labels)
    # Add a title.
    plt.title('IP address activity')
    # Display the pie chart.
    plt.show()
Main()

代码打印到终端并写入文本文件，但它不绘制饼图。另外，我试图弄清楚如何允许用户选择以是或否的形式保存到文本文件，而不是仅仅按照当前设置强制写入，我会添加另一个嵌套的 if else 语句吗？

这对我有用:

import subprocess
import matplotlib.pyplot as plt
from pathlib import Path
from collections import Counter

addresses = Path('ipaddress.txt')
counter = Counter(a=0, i=0)

with addresses.open('w') as f:
    for n in range(1, 100):
        ip = f'192.168.1.{n}'

        cmd = subprocess.run(
            ['ping', '-n', '1', '-w', '200', ip],
            stdout=subprocess.DEVNULL,
            stderr=subprocess.DEVNULL
        )

        if cmd.returncode:
            print(f'{ip} inactive')
            f.write(f'{ip} inactive\n')
            counter.update('i')
        else:
            print(f'{ip} active')
            f.write(f'{ip} active\n')
            counter.update('a')

labels = ['Active', 'Inactive']
plt.pie(counter.values(), labels=labels)
plt.title('IP address activity')
plt.show()

希望对您有所帮助。
