解釋下 FolderNum = .[F20].End(3).Row - 1
时间: 2024-05-31 17:10:08 浏览: 57
这是一段 Excel VBA 代码,它的作用是计算一个名为"F20"的列中有多少个非空单元格。
具体解释如下:
1. ".[F20]"表示当前活动工作表中名为"F20"的列。这是一种简写方式,相当于"ActiveSheet.Range("F20")"。
2. ".End(3)"表示向下搜索,直到找到最后一个非空单元格,返回该单元格的 Range 对象。数字 3 表示搜索方向为向下,参考该文档。
3. ".Row"表示返回 Range 对象的行数,即最后一个非空单元格所在的行号。
4. "-1"表示将上一步计算出的行数减去 1,是因为第一行通常是标题行,所以不计入统计。
综上,这段代码的作用是计算当前活动工作表中名为"F20"的列中,除了标题行之外有多少个非空单元格。计算结果存储在变量 FolderNum 中。

问题: 这个错误的原因是什么?如何解决?
回答: 这个错误的原因是Python中的ssl模块不可用。解决这个问题的方法是在pip命令中加上--trusted-host参数,表示信任镜像文件。具体命令如下:pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pip -U --trusted-host pypi.tuna.tsinghua.edu.cn。这样就可以解决这个错误了。
