如何在写入函数末尾添加变量并将其放置循环

Question

我正在使用 telnetlib.Telnet 函数连接到 telnet 设备，但我不知道如何在写入函数末尾添加变量，我看到 How do I put a variable inside a string? bu 对我没有帮助，所以这是我的代码

def h4ck_th3_w0rld(HOST):
    user = 'admin'
    password = 'password'
    tn = None
    try:
        tn = telnetlib.Telnet(HOST, 23, 11)
 
        tn.read_until("Username: ", 7)
        tn.write(user + "\n")
        if password:
            tn.read_until("Password: ", 7)
            tn.write(password + "\n")

    for i in range(100, 256):
        for j in range(7, 7):
            ip_addressa = '192.168.%d.%d' % (j, i)
            h4ck_th3_w0rld(ip_addressa)
            print(ip_addressa)

    tn.write("cd /var/tmp\n")
    tn.write("./busybox telnet {}\n"(ip_addressa)) <--- here add ip_addressa variable
        tn.write("exit\n")

我需要将 /var/tmp/busybox telnet 172.24.%d.%d 放在一边的 while 循环中并请求看起来像这样

./busybox telnet 192.168.7.100
./busybox telnet 192.168.7.101

你需要连接它：

tn.write("./busybox telnet " + ip_addressa + "\n")

或使用format():

tn.write("./busybox telnet {}\n".format(ip_addressa))
