當我們所需要替換的數據量比較大的時候，使用excel中自帶的替換功能會發現非常耗時，這時可以使用python，快準狠！

#coding=utf-8

import xlrd

import codecs

import re

def open_xlsx():

# 加載Excel數據，處理數據

data = xlrd.open_workbook('測試.xlsx') # 讀取工作表

table = data.sheet_by_name('Sheet1') # 讀取當前sheet表對象

rows = table.nrows # 獲取行數

print('一共有{}行數據，開始清洗數據'.format(rows))

for i in range(1,rows):

company = table.row_values(i)[0]

job = table.row_values(i)[1]

degree = table.row_values(i)[2]

fuli = table.row_values(i)[3]

salary = table.row_values(i)[4]

experience = table.row_values(i)[5]

area = table.row_values(i)[6]

zhize = table.row_values(i)[7]

yaoqiu = table.row_values(i)[8]

degree = degree.replace("?"," ")

experience = experience.replace("?"," ")

area = area.replace("?"," ")

zhize =zhize.replace("?"," ").replace("["," ").replace("]"," ")

yaoqiu = yaoqiu.replace("?"," ").replace("["," ").replace("]"," ")

output = ('{}\t{}\t{}\t{}\t{}\t{}\t{}\t{}\t{}\n').format(company, job, degree, fuli, salary, experience, area, zhize, yaoqiu)

f = codecs.open('清洗后的數據.xls', 'a+')

f.write(output)

f.close()

if __name__ == '__main__':

open_xlsx()
