如何以编程方式获取登录 linux 机器的用户数？

import subprocess

def get_logged_in_users():
    output = subprocess.check_output(["who"])
    return output.decode("utf-8").count("\n")

user_count = get_logged_in_users()
print(f"当前登录用户数：{user_count}")

pip install python-utmp

import utmp
import os

def get_logged_in_users():
    user_count = 0
    with utmp.UtmpFile() as uf:
        for entry in uf:
            if isinstance(entry, utmp.UtmpEntry):
                user_count += 1
    return user_count

user_count = get_logged_in_users()
print(f"当前登录用户数：{user_count}")
