Python提取Excel指定关键词行数据：从基础到进阶方案

import xlrd
import xlwt

data = xlrd.open_workbook(r'shuju.xlsx')
rtable = data.sheets()[0]
wbook = xlwt.Workbook(encoding='utf-8',style_compression = 0)
wtable = wbook.add_sheet('sheet1',cell_overwrite_ok = True)

count = 0
keyword = ('python')
keyword1 = ('ubuntu')  #可添加多个关键词
for i in range(0,40):  #区域按数据包含的行数进行填写，过多会显示超出范围（out of range）
    if rtable.cell(i,2).value == keyword or rtable.cell(i,3).value == keyword or rtable.cell(i,4).value == keyword or rtable.cell(i,5).value == keyword or rtable.cell(i,2).value == keyword1 or rtable.cell(i,3).value == keyword1 or rtable.cell(i,4).value == keyword1 or rtable.cell(i,5).value == keyword1:
        for j in range(0,5):
            wtable.write(i,j,rtable.row_values(i)[j])
        count += 1
print (count)
wbook.save(r'medicaldata.xls')
