Django views.py invalid syntax

问题

I want to send email to multiple recipients in Django, using SendGrid.

In my views.py file I have this and it works:

data = {
    "personalizations": [
        {
            "to": [
                {"email": "address@example.com"},
                {"email": "address2@example.com"},
            ],
            "subject": "New message
        }
    ],
    "from": {
        "email": email
    },
    "content": [
        {
            "type": "text/plain",
            "value": message
        }
    ]
}

But I want to add addresses from loop. So, I use:

"to": [
    for address in addresses:
        {"email": address},
],

and I get the following error:

    for address in addresses:
      ^
SyntaxError: invalid syntax

What is the correct syntax?

回答1:

You can try list comprehension

"to": [{"email": address} for address in addresses]
