在你的代码中，`characters1` 是在 `root_password` 类内部定义的局部变量。如果你想从外部访问它，你需要将其定义为类的属性。你可以通过在 `characters1` 前面加上 `self.` 来实现。修改后的代码如下所示：

# encoding: utf-8
import time
import os
import random
import subprocess

class root_password:
    Ap = 'QAZWSXEDCRFVTGBYHNUJMIKOLP'
    Bp = 'qazwsxedcrfvtgbyhnujmikolp'
    Cp = '!@#$%^&*'
    Dp = '0123456789'

    def __init__(self):
        self.characters = 'QAZWSXEDCRFVTGBYHNUJMIKLOP'
        self.Dpass = random.choice(self.characters)
        print(self.Dpass)
        self.characters = '!@$%^&*'
        self.fpass = ''.join(random.choice(self.characters))
        print(self.fpass)
        self.characters1 = self.Bp + self.Ap
        self.passfa1 = ''.join(random.choice(self.characters1) for _ in range(2))
        print(self.passfa1)
        self.characters2 = self.Bp + self.Dp
        self.passfa2 = ''.join(random.choice(self.characters2) for _ in range(2))
        print(self.passfa2)
        self.characters3 = self.Bp + self.Cp
        self.passfa3 = ''.join(random.choice(self.characters3) for _ in range(3))
        print(self.passfa3)
        self.characters4 = self.Ap + self.Dp
        self.passfa4 = ''.join(random.choice(self.characters4) for _ in range(2))
        print(self.passfa4)
        self.characters5 = self.Ap + self.Cp
        self.passfa5 = ''.join(random.choice(self.characters5) for _ in range(2))
        print(self.passfa5)
        self.characters6 = self.Dp + self.Cp
        self.passfa6 = ''.join(random.choice(self.characters6) for _ in range(3))
        print(self.passfa6)
        self.NEWPASS = self.Dpass + self.passfa3 + self.passfa6 + self.fpass + self.passfa1 + self.passfa4 + self.passfa5
        print(self.NEWPASS)
        command = 'echo ' + self.NEWPASS + ' | sudo passwd --stdin root'
        subprocess.run(command, shell=True, stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)
        command1 = 'echo ' + time.strftime('%Y-%m-%d %H:%M', time.localtime(time.time())) + '--root >> /root/pass.log'
        command2 = 'echo ' + self.NEWPASS + ' >> /root/pass.log'
        subprocess.run(command1, shell=True, stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)
        subprocess.run(command2, shell=True, stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)

然后，你可以通过以下方式导入 `root_password` 类并使用它：

from root_password import root_password

rp = root_password()

这样就可以成功创建 `root_password` 类的实例，并执行其中的代码了。
