Python学习_几种存取xls/xlsx文件的方法总结

import xlwt  workbook = xlwt.Workbook(encoding='utf-8') booksheet = workbook.add_sheet('Sheet 1', cell_overwrite_ok=True) #存第一行cell(1,1)和cell(1,2) booksheet.write(0,0,34) booksheet.write(0,1,38) #存第二行cell(2,1)和cell(2,2) booksheet.write(1,0,36) booksheet.write(1,1,39) #存一行数据 rowdata = [43,56] for i in range(len(rowdata)):  booksheet.write(2,i,rowdata[i]) workbook.save('test_xlwt.xls') 

import xlrdworkbook = xlrd.open_workbook('D://Py_exercise//test_xlwt.xls')print(workbook.sheet_names())  #查看所有sheetbooksheet = workbook.sheet_by_index(0) #用索引取第一个sheetbooksheet = workbook.sheet_by_name('Sheet 1') #或用名称取sheet#读单元格数据cell_11 = booksheet.cell_value(0,0)cell_21 = booksheet.cell_value(1,0)#读一行数据row_3 = booksheet.row_values(2)print(cell_11, cell_21, row_3)>>>34.0 36.0 [43.0, 56.0]
