Python运用webbrowser打开PyEcharts生成的html文件

话不多说，直接上代码

这里 也有更多pyecharts的代码~

示例

调用库

import pandas as pd import time from functools import partial from PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGui, QtWidgets from pyecharts import options as opts from pyecharts.charts import Kline, Line, Bar, Grid import webbrowser as wb
