建立py文件app

from flask import Flask
from flask import render_template

app = Flask(__name__)

@app.route('/test')
def test():
    name = 'Tom'
    gender = 'male'
    age = 23
    return render_template('test.html',name = name, gender = gender, age =age)

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

在相同的目录里创建文件夹static和templates，flask会自动调用


static里面放前端格式css文件
tenplates里面放html要实现的文件
test.html


```python
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>测试页面</title>
</head>
<body>
    <p>
        <h3>用户信息</h3>
        姓名：<strong>{
   {
    name }}</strong>
        <br>
        性别：<span style="color:red;">{
   {
    gender }}</span>
        <br>
        年龄：{
   {
    age }}
    </p>

</body>
</html>

就ok啦
