标签:格式化 war dex 日期 mamicode number 功能 判断 数据类型 Python读取Excel,里面如果是日期,直接读出来是float类型,无法直接使用。 通过判断读取表格的数据类型ctype,进一步处理。 返回的单元格内容的类型有5种: ctype: 0 empty,1 string, 2 number, 3 date, 4 boolean, 5 error ctype =sheet1.cell(iRow,iCol).ctype 参考示例如下: 1.准备一个Excel文件,文件名Book1.xlsx 从第2行的第1列开始向右,分别是2019年的7月的1、2、3、4日,2019-07-01、2019-07-02、2019-07-03、2019-07-04 A列单元格的类型:date B列单元格的类型:Text C列单元格的类型:Text D列单元格的类型:Custom里的一种日期格式 2.Python文件,ReadExcelDemo.py,代码如下: 3.执行结果: Python读取Excel,日期列读出来是数字的处理 标签:格式化 war dex 日期 mamicode number 功能 判断 数据类型 原文地址:https://www.cnblogs.com/SH170706/p/11133525.html#! -*- coding utf-8 -*-
