问用Python SMTP发送我的第一封电子邮件-使用"with“是无效的语法吗？

EN

from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import smtplib

#Replaced email, name, & password w/ filler

message = MIMEMultipart()
message["from"] = "First_Name Last_Name"
message["to"] = "email@email.com"
message["subject"] = "This is a test"
message.attach(MIMEText("Body")

with smtplib.SMTP(host="smtp.gmail.com", port=587) as smtp:
    smtp.ehlo()
    smtp.starttls()
    smtp.login("email@email.com", "password1234")
    smtp.send_message(message)
    print("Sent...")

  File "c:\Users\Mofongo\Google Drive\HelloWorld\app.py", line 11
    with smtplib.SMTP(host="smtp.gmail.com", port=587) as smtp:
