python之数据驱动Txt操作

一、新建数据Mail163.txt文本

 二、Txt_Mail163.py脚本如下：

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

#未封装的读取文本信息方法
# with open('Mail163.txt', 'r', encoding='utf-8') as fp:
#     file = fp.readlines()
#     aa = ''.join(file).split('
')
#     print(aa[2],type(aa[2]))


def MailInfo(index):
    '''封装读取文本信息方法,index为读取的行数'''
    with open('Mail163.txt','r',encoding='utf-8') as fp:
        file = fp.readlines()
        aa = "".join(file).split('
')
        return aa[index]

#报错信息 --添加encoding='utf-8'
#UnicodeDecodeError: 'gbk' codec can't decode byte 0xb7 in position 29: illegal multibyte sequence
# print(MailInfo(2))
#字符串切割
 -->用split('
')
#['
', 'admin
', '^^^^
', '请输入帐号
', '请输入密码
', '帐号格式错误']
