通过此案例就可以知道如何使用：

test.py

#!/usr/bin/python
    # coding: utf-8
    from flask import Flask,render_template,url_for
    #生成Flask实例
    app = Flask(__name__)
    @app.route('/')
    def my_echart():
    #在浏览器上渲染my_templaces.html模板
        return render_template('my_template.html')
    
    if __name__ == "__main__":
        #运行项目
        app.run(debug = True)

在render\_templates:  文件夹下：
