Python/Django : Unable to return list elements line by line

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。

但是当我尝试逐行返回 HTTPResponse 中的列表元素时，它会在单行中提供所有内容。

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]]))

输入是从城市变量中的用户处获取的，如下所示: 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

请告知，当我返回 HTTPResponse 时，我该怎么做才能在浏览器上显示城市。

谢谢!

\n在您的 HTML 中没有任何意义回复。使用<br>而是用标签分隔行。
