Python处理Excel数据：基于xlrd与xlwt的去重及求和实现

#coding:utf-8
import xlrd
import xlwt

from collections import Counter
workbook = xlrd.open_workbook(r'D:\hh\heli\a.xlsx')

clos_b=Sheet1.col_values(4)
clos_c=Sheet1.col_values(5)
wbk = xlwt.Workbook()
sheet = wbk.add_sheet(u'初始表')
sheet.write(0, 0, u'小区')
sheet.write(0, 1, u'总端口数')
sheet.write(0, 2, u'已使用端口数')
test=('D:\hh\heli\\美女你好.xls').decode('utf-8') #表名是不是让你想入非非了，哈哈
result = []
