使用 openpyxl 格式化日期

Question

您好，我正在尝试创建一个 python 程序，该程序使用 openpyxl 来验证 excel 表中的两个单元格 (1)start_date 和 (2)end_date，以检查 current_date 是否介于两者之间。有人对我如何做到这一点有任何指示吗？

我无法将日期转换为我可以操作的变量。当我把这行：

B2 包含一个日期

日期 = 打印(sheet_ranges["B2"].value)

然后日期等于“无”

所以任何帮助都会非常感谢您。

我想说你只需要摆脱你的print：

date = sheet_ranges["B2"].value

print 返回None，这就是为什么您要获取该值，而不是单元格中的值。
