python之数据驱动Excel操作（方法一）

一、Mail163.xlsx数据如下:

二、Mail163.py脚本如下

import xlrd
import unittest
from selenium import webdriver
from selenium.webdriver.common.by import By
import time

#安装:pip install xlrd

    '''读取Excel数据'''
    table = xlrd.open_workbook('Mail163.xlsx','r')
    sheet = table.sheet_by_index(0)
    return sheet.row_values(nrow)

def readusername(nrow):
    '''读取用户名数据'''
    return readExcel(nrow)[0]

def readpassword(nrow):
    '''读取密码数据'''
    return readExcel(nrow)[1]

def readresult(nrow):
    '''读取预期结果数据'''
    return readExcel(nrow)[2]

        self.driver.switch_to_frame(iframe)

        except Exception as msg:
            print("断言失败{}".format(msg))
        self.driver.switch_to_default_content()
