改进Python代码更新谷歌电子表格

首先，我是python的新手（实际上我只从Sololearn那里学到，也只能学到一半的课程）。 所以我请你给我一点详细的答案。 我的任务有以下几个步骤：

1. 删除旧的.xlsx文件（如果有的话）

2. 使用win32将两个.xls文件转换成.xlsx文件，删除第一行，然后删除.xls文件[已经下载到源代码目录xlrd的xls文件，pyexcel在打开.xls文件中显示错误（不受支持的格式或损坏）在线分析文件预测为html / htm）]

3. 从xlsx文件获取数据

4. 首先，删除Google电子表格上的旧工作表以删除旧数据。 创build一个具有相同名称的新工作表。 将数据插入到Google电子表格的新工作表中。

5. 打开第二张表格（从第一张表格导入数据）并更新“虚拟表格”中的一个单元格，以确保Google电子表格在后台同步。

现在，我通过结合许多代码和使用大量的谷歌来编写代码。 代码工作正常，但需要平均约65秒来完成整个过程。 我的问题有3个部分：

1. 有没有办法直接从.xls文件中访问数据？
2. 有什么办法可以改善这个代码的性能。
3. 任何其他更有效的方法来完成上述任务？

我的代码： –
