flask的模板渲染

from flask import Flask, render_template, Markup# markup相当于django的reverse

app = Flask(__name__)

app.debug = True

USERS = {
    1:{'name':'张三','age':18,'gender':'男','text':"道路千万条"},
    2:{'name':'李四','age':28,'gender':'男','text':"安全第一条"},
    3:{'name':'王五','age':18,'gender':'女','text':"行车不规范"},
}

def func1(arg, tank):
    # Markup可以支持前端的代码在后端书写
    return Markup(f"<h1>alen真的好帅啊, {arg} is sb {tank} is same as {arg}</h1>")


@app.route('/')
def index():
    # data = {
    #     "user" :USERS,
    #     "name": "jason"
    # }
    return render_template('index.html', user=USERS, name="jason",ht1=func1, ht="<h1>alen真帅啊</h1>")
    # return render_template('index.html', **data)


if __name__ == '__main__':
    app.run()

<table>
{% for k,v in user.items() %}
   <tr>
