Python实现Excel随机抽取数

有这样一组数据：



现在要随机抽取十个数字，代码如下：

import sys
import xlrd
import random

print("pm2.5 天津")
#打开Excel
workbook = xlrd.open_workbook('2.xls')

#进入sheet
excel_sheet = workbook.sheet_by_index(0)

#获取行数和列叔
nrows_num = excel_sheet.nrows
ncols_num = excel_sheet.ncols
i=1
while 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].value
name = excel_sheet.row(random_num)[2].value
print(number,name)
# print(name)
i = i + 1
else:
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。
