过去，在很多金融、市场、行政的招聘中，面试官都会问一句：“你精通 EXCEL 吗？” 但今天，他们可能更喜欢问：“你会 Python 吗？” 越来越多的企业开始用 Python 处理数据，特别是金融、证券、商业、互联网等领域。 在顶级公司的高端职位中，Python 更是成为了标配： Python 究竟有什么法力能让大家如此青睐？ 举个例子：在过去，如果老板想要获取 A 股所有股票近 2 年的数据，你可能需要 登录-查询-下载-记录到excel 循环 500 多次，即使你是一个没有感情的复制机器人，也需要一两天的时间。 但如果你掌握了 Python，只需要写个脚本，**泡杯咖啡的功夫 **数据就全部下载好了。 再加上 Python 强大的绘图功能，你可以一次性完成 数据收集 — 整理 — 分析 — 绘图 的过程，直接把分析结果用图表呈现出来。 今天本篇文章，我们就总结了一下利用 python 操作 Excel 文件的第三方库和方法。 内容出自课程—— 《OpenPyXL 处理 Excel 基础入门》 ，欢迎大家来实验边敲代码边学习～ 首先，我们来学习一下，如何 用 Python 创建和保存 Excel 文档。 对于经常与数据打交道的人来说，Excel 是经常使用的工具；对于与数据打交道的程序员来说，OpenPyXL 库是一个利器。Python 官方提供了这样一个库，让我们可以直接通过

Applying row height to all rows including and after row 7

由 左心房为你撑大大i 提交于 2020-05-31 03:41:52
问题 I cannot figure out how to apply a row height on an existing worksheet unless I do it one row at a time. This works for a single row: ws4.row_dimensions[14].height = 25 But I want to set the row height for row 7 and any subsequent rows. This approach does nothing yet does not throw an error: for rows in ws4.iter_rows(min_row=7, max_row=None): ws4.row_dimensions.height = 25 wb4.save('C:\\folder\\DataplusRows.xlsx') Any idea how to do this? I can't glean the answer from the openpyxl
