<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
Hello world
<br>
{{ data.name }}
<br>
{{ data.age }}
<br>
{{ data.list[1] }}
<br>
{{ "hello_world" | upper }}

</body>
</html>

from flask import Flask, render_template

app = Flask(__name__)


@app.route("/index")
def index():
    data = {
        'name': "张三",
        "age": 18,
        'list': [123123,41,123]
    }
    return render_template("index2.html", data=data)


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

就可以看到大写的内容
