继承页面 （super()用于显示base.jinja2中原有的内容，这里为1234）
// index.jinja2
{% extends ‘base.jinja2‘ %} {% block title -%} {{ super() }} Name: {{ name|title }} {%- endblock %} {% block main %} {% for item in items %} {{ item }} {% endfor %} {% endblock %}
后端业务测试代码
from flask import render_template @app.route(‘/‘) def index(): return render_template(‘index.jinja2‘, name=‘bob‘, items=range(10))
