Python/Django: 无法 return 逐行列出元素

Question

我正在尝试从 json 文件中过滤城市，并在 Django 应用程序的帮助下显示过滤列表中的前五个城市。

但是当我尝试 return 逐行列出 HTTPResponse 中的元素时，它会在一行中给出所有内容。

views.py 文件

from django.http import HttpResponse
import re
import os
from django.conf import settings

def index(request):
    a= str(request.GET['city'])
    with open(os.path.join(settings.MEDIA_ROOT, 'all_city_info.json')) as f:
        data = f.read()

    lis=sorted(x[9:-1] for x in re.findall('"text": "'+re.escape(a)+'[\s\S]+?"', data))
    return HttpResponse('\n'.join([str(x) for x in lis[:5]]))

城市变量中的用户输入是这样的： http://127.0.0.1:8000/api/?city=New

我得到的结果：

New York Mills|Minnesota|United States New York Mills|New York|United States New York|New York|United States New York|Norfolk|United Kingdom

请指教，当我 return HTTPResponse.

时，我该怎么做才能在浏览器上显示城市？

谢谢！

示例数据，如果有人想看一下-

\n 在您的 HTML 回复中没有任何意义。使用 <br> 标签来分隔行。
