Django views.py無效語法

Question

我想使用SendGrid將電子郵件發送給Django中的多個收件人。

在我views.py文件我也這樣與它的工作原理：

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

但我想從循環添加地址。所以，我用：

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

，我得到以下錯誤：

for address in addresses: 
    ^
SyntaxError: invalid syntax 

什麼是正確的語法？

Answer 1

您可以嘗試list comprehension

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