Python 3.x Typeerror:新闻对象不可编辑

我正在尝试从新闻api获取新闻，我已将函数设置为返回一个新闻结果数组。我想显示新闻的显示模板中出现错误

def getNews():
  '''
  function that fetches all news
  '''

  with urllib.request.urlopen(news_url+'281dbdc2e10e4a6ab51a9a27a614c146') as me:
    news_data = me.read()
    news_response = json.loads(news_data)

    all_news = None

    if news_response['articles']:
      all_news_list = news_response['articles']
      all_news_data = process_news(all_news_list)

  return all_news

def process_news(news_list):

  all_news = []
  for news in news_list:
    author = news.get('author')
    title = news.get('title')
    description = news.get('description')
    url = news.get('url')
    urlToImage = news.get('urlToImage')
    publishedAt = news.get('publishedAt')

    if author:
      news_object = Article(author,title,description,url,urlToImage,publishedAt)
      all_news.append(news_object)

  return all_news

@makozaki给定代码，

getNews

将始终返回

None

all\u news

在返回之前不会重新分配。您必须了解

all\u news

在这两种方法中都是局部变量。您必须从

getNews

返回

all\u news\u data

，这是

process\u news

的实际输出。

@main.route('/')
def index():
  news = getNews()
  title = "All News"
  return render_template('index.html',news=news,title=title)

{% for myNews in news %}
{% endfor %}
