python - smtplib.SMTPConnectError: (421, b'无法连接到 SMTP 服务器 2a00:1450:400c:c09::6c (2a00:1450:400c:c09::6c:25)，连接错误 10060')

Question

我想知道为什么这段代码不起作用。我在 VSCode，python 3.8.0-32bit。我不知道这个问题是来自代码还是来自我应该对我的 gmail 执行的操作。你能告诉我这个吗

sender_email = input(str("enter your email address: "))
password = input(str("enter your password: "))
rec_email = input(str("enter the email address to whom you want to send the message: "))
message = str("message envoyé avec python")
print(".")
server = smtplib.SMTP('smtp.gmail.com')
print(".")
server.starttls()
print(".")
server.login(sender_email,password)
print("login success")
server.sendmail(sender_email,rec_email,message)
print("email has be sent to", rec_email)```
And python sends me back:

我的 Outlook 设置显示服务器“smtp.gmail.com”使用端口 465 和 SSL/TLS 加密。因此我使用：server = smtplib.SMTP_SSL('smtp.gmail.com') 而不是：server = smtplib.SMTP('smtp.gmail.com') server.starttls()。作为这个主题的新手，我在How to send an email with Gmail as provider using Python? 下找到了这个解决方案？.
