前言
手里有一点点公司的股票, 拿不准在什么时机抛售, 程序员也没时间天天盯着看,不如动手写个小程序, 把股票趋势每天早上发到邮箱里,用 python 的 pandas, matplotlib 写起来很容易, 几十行代码搞定。
准备环境
python3 -m venv venvsource ./venv/bin/activatepip install pandaspip install pandas_datareaderpip install matplotlib
代码如下
绘制 2019 年到今天2019-02-15 的我司 ( Cisco ) 的股票趋势 ( open:开盘价, close: 收盘价, high 最高价:, low: 最低价,单位为美元)
$ vi stock.py

运行命令如下
python stock.py -c CSCO -s 2019-01-01 -e 2019-02-19 -f cisco_stock_trend.png
图表如下
