如何将 IP 地址列表绘制为活动或非活动并保存到文本文件

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，但它没有绘制饼图。此外，我试图弄清楚我将如何允许用户选择将保存到文本文件的选项作为是或否，而不是像当前设置的那样强制写入，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()

希望对你有帮助。
