如何创建excel文件然后通过数据框读取文件？

Question

I have 20 symbols for which I need to record tick data continuously for 6 hours a day every week. So I want 20 excel files to be created automatically by the module (if files don't exist) and a excel writer which stores tick data (row by row). Then I need to resample the data to 5 minutes timeframe after reading them through dataframe. Dataframe should be able to read the tick data created by the module.

What best excel writer can be used for this function. I want to write to the files when they are closed.

which of them will work better?

1. In built open function
2. Openpyxl
3. Xlwt
