Zvt 既提供了可视化的历史数据浏览方式（web），又提供了A股历史数据的获取接口，是一个好用的股票数据下载工具。
它的使用方式非常简单，下面就教大家如何安装使用这个模块。
1.准备
开始之前，你要确保Python和pip已经成功安装在电脑上，如果没有，请访问这篇文章：超详细Python安装指南 进行安装。
(可选1) 如果你用Python的目的是数据分析，可以直接安装Anaconda：Python数据分析与挖掘好帮手—Anaconda，它内置了Python和pip.
(可选2) 此外，推荐大家用VSCode编辑器来编写小型Python项目：Python 编程的最好搭档—VSCode 详细指南
Windows环境下打开Cmd(开始—运行—CMD)，苹果系统环境下请打开Terminal(command+空格输入Terminal)，输入命令安装依赖：
x
pip install -U zvt注意，Python版本最好大于等于Python3.6.
2.Zvt Web 界面
如果你想要进入web界面，在安装完成模块后，重启终端，进入你的zvt所属Python环境，执行下面这行命令：
zvt然后打开 http://127.0.0.1:8050/ 就能看到相关的图表：
3.Zvt 获取数据
想要通过Zvt获取A股股票的基本数据，你只需要这样：
