【python web】Flask+Echarts 实现动图图表
flask 是python web开发的微框架，Echarts酷炫的功能主要是javascript起作用，将两者结合起来，发挥的作用更大。下面将Echarts嵌套进Flask的html模板中。
项目结构：
打开demo.py运行，点击console中的链接http://127.0.0.1:5000/ 就可以看到我们想要的动态图表。
demo.py
#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)my_template.html
