摘要：from django.urls import path, re_path, include from mysite import viewsurlpatterns = [re_path(r"^mytest$", views.mytest), ] from django.shortcuts import renderdef mytest(request):ls = ["北京", "上海", "天津", "

在這里插入圖片描述

from django.urls import path, re_path, include
from mysite import viewsurlpatterns = [re_path(r"^mytest$", views.mytest),
]

from django.shortcuts import renderdef mytest(request):ls = ["北京", "上海", "天津", "深圳", "紐約"]return render(request, "fortest.html", locals())

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Title</title>
</head>
<body><ul>{% for city in ls %}<li>{{ city }}</li>{% empty %}<li>沒有城市</li>{% endfor %}</ul>
</body>
</html>

django網站模板下載、注：通過for標簽，可以根據列表ls的情況動態生成HTML

        {% for city in ls %}<li>{{ city }}</li>{% endfor %}

在這里插入圖片描述

        {% for city in ls %}<li>{{ forloop.counter }}、{{ city }}</li>{% endfor %}

        {% for city in ls %}{% if forloop.first %}<li>---------</li>{% endif %}<li>{{ forloop.counter }}、{{ city }}</li>{% if forloop.last %}<li>~~~~~~~~~</li>{% endif %}{% empty %}<li>沒有城市</li>{% endfor %}
