Python3读写Excel文件(使用xlrd,xlsxwriter,openpyxl3种方式读写实例与优劣)

 import xlrd

 xlrd.open_workbook(r'/root/excel/chat.xls')

 # 获取所有sheet sheet_name = workbook.sheet_names()[0] # 根据sheet索引或者名称获取sheet内容 sheet = workbook.sheet_by_index(0) # sheet索引从0开始

 # 获取整行和整列的值（数组） rows = sheet.row_values(1) # 获取第2行内容 cols = sheet.col_values(2) # 获取第3列内容

 # sheet的名称，行数，列数 print (sheet.name,sheet.nrows,sheet.ncols)
