xlwings

问题 I have an Excel open which has RTD streaming data (financial data from a trading platform). My goal is read the data by Python and save it as soon as it changes.

问题 I'm trying to use xlwings for the first time but I can't quite understand the documentation. From the section "Quickstart" I read import xlwings as xw wb = xw.Book() # this will create a new workbook When I try this "at home", I have no problem importing xlwings but with the second script I get this error: AttributeError: module 'xlwings' has no attribute 'Book' When I try to see the attributes of xw I can see AboveBelow,ActionTime etc. but not Book. Can you help please? Thank you very much.
