import xlwt

import xlrd

import re

workbook = xlrd.open_workbook('data.xlsx')

sheet = workbook.sheet_by_index(0)

data = []

for rx in range(0, sheet.nrows):

    row = sheet.row(rx)

    item = []

    for cx in row:

        item.append(cx)

    data.append(item)

workbook = xlwt.Workbook()

sheet = workbook.add_sheet('output')

rIndex = 0

for row in iter(data):

    cIndex = 0

    for cel in row:

        sheet.write(rIndex, cIndex, cel.value + " changed")

        cIndex += 1

    rIndex += 1

workbook.save('data_output_1.xls')

Python 正则表达式

查找val中是否存在xxx

import re

ret = bool(re.search(r'xxx', val))
