The code snippet is as follows: from openpyxl import loadworkbook wb = loadworkbook(filename = 'largefile.xlsx', useiterators = True) ws = wb.getsheetbyname(name = 'bigdata'). 使用openpyxl没有必要先在系统中新建一个.xlsx,我们需要做的只需要引入Workbook这个类,接着开始调用它。 from openpyxl import Workbook wb = Workbook 一个工作簿(workbook)在创建的时候同时至少也新建了一张工作表(worksheet)。.
