有这样一组数据：
现在要随机抽取十个数字，代码如下：
import sysimport xlrdimport randomprint("pm2.5 天津")#打开Excelworkbook = xlrd.open_workbook('2.xls')#进入sheetexcel_sheet = workbook.sheet_by_index(0)#获取行数和列叔nrows_num = excel_sheet.nrowsncols_num = excel_sheet.ncolsi=1while i<=10:if nrows_num > 10:#生成随机数random_num = random.randint(1,nrows_num-1)number = excel_sheet.row(random_num)[1].valuename = excel_sheet.row(random_num)[2].valueprint(number,name)# print(name)i = i + 1else:print("数据不足，请添加")break
运行：
pm2.5 天津
35.92 0.3129
79.1866 0.253475
121.7066 0.125175
91.6 0.541348
121.7066 0.125175
162.2133 0.917009
21.56 0.0599271
130.4666 0.338327
58.7733 0.382621
66.8666 0.703601
即可实现。
