python使用xlrd模块读取xlsx文件中的ip方法

#coding=utf8

import xlrd
from os import path
import sys

filename='ip.xlsx'
if not path.isfile(filename):
 print "err: not exists or not file ip.xlsx "
 sys.exit()

getfile=xlrd.open_workbook(filename)
table=getfile.sheet_by_index(0)
rows=table.nrows
#cols=table.ncols 若有多列，再加一层for循环
for i in xrange(rows):
 cell_vlaues=table.cell_value(i,0)
 print cell_vlaues
