flask中的如何将后端写前端的代码设置session

from flask import Flask,render_template,request,redirect,jsonify,views,url_for,Markup
from werkzeug.routing import BaseConverter

#匹配正则表达式需要填写的参数
app = Flask(import_name=__name__)
#app.secret_key = 'sdfsdfsdfsdf',设置session的值

#Markup可以将后端的代码写前端的语言到前端渲染
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(st,st1):
    return Markup(f"<h1>jsaon-gdx{st}{st1}</h1>")

@app.route('/list',methods=['GET'])
def list():
    info=USERS

    return render_template('list.html',info=info,html="<h1>jsaon-gdx</h1>",html1=func1)
@app.route('/detail/<int:nid>',methods=['GET'],endpoint="sb")
def detail(nid):

    return "ok"
