python之数据驱动Excel+ddt操作（方法二）

一、Mail163数据如下:

二、Excel+ddt代码如下：

import xlrd
import unittest
from selenium import webdriver
from selenium.webdriver.common.by import By
from ddt import ddt,data,unpack
import time

#安装:pip install xlrd
#读取的数据存储在list表中
def readExcels():
    table = xlrd.open_workbook('Mail163.xlsx','r')
    sheet = table.sheet_by_index(0)
    nrow = [] #定义空列表
    for row in range(1,sheet.nrows): #从1-N行读取遍历数据
        #sheet.row_values(1,0,2)从0-2列读取数据成列表
        nrow.append(sheet.row_values(row,start_colx=0,end_colx=sheet.ncols))
    return nrow
# print(readExcels())
#[['', '', '请输入账号'], ['admin', '', '请输入密码'], ['', 'admin', '请输入账号'], ['^^^^', '', '账号格式错误']]

        except Exception as msg:
