Python是纯粹的自由软件, 源代码和解释器CPython遵循 GPL(GNU General Public License)协议。Python语法简洁清晰,特色之一是强制用空白符(white space)作为语句缩进。

Python具有丰富和强大的库。它常被昵称为胶水语言,能够把用其他语言制作的各种模块(尤其是C/C++)很轻松地联结在一起。常见的一种应用情形是,使用Python快速生成程序的原型(有时甚至是程序的最终界面),然后对其中有特别要求的部分,用更合适的语言改写,比如3D游戏中的图形渲染模块,性能要求特别高,就可以用C/C++重写,而后封装为Python可以调用的扩展类库。需要注意的是在您使用扩展类库时可能需要考虑平台问题,某些可能不提供跨平台的实现。

Python是一种面向对象的解释型计算机程序设计语言,它语法简洁清晰,具有丰富和强大的库。《马哥教育python基础语法全讲解视频》带你由浅至深的学习python基础语法,深刻体会Python语言的特点。

引用excel表格

  1、需要下载xlrd;

  2、引用xlrd库:import xlrd

  3、获取excel表值:

bk = xlrd.open_workbook('D:\\del_tools\\python\\setup\\test\\data.xls')  #打开excel表
sh = bk.sheet_by_name('Sheet1')  #打开表格的工作表
usermobile = sh.cell_value(1,0)  #获取工作表中对应表格的值<br><br>#注意:uesermobile的类型是float,如果是手机号的话,这个值会显示为13800138000.0;<br><br>
#send_keys()方法中,参数要求是string 类型的,所以这里要将float类型转换为string类型:str(int(float x ));

四、处理首页弹窗

  思路:查看首页是否存在没弹窗时的元素,存在则表示没有弹窗,不存在则表示存在弹窗。

  实例:

#处理开屏广告def init_case(self):    print(u&#39;处理开屏广告&#39;)    try:
        sleep(3)        #查看弹窗是否存在
        el = self.driver.find_element_by_id("id/llStorage")        print "not exict"
        pass
Copy after login

except Exception,ex:

 sleep(3)
        os.system("adb shell input tap"+" "+str(629)+" "+str(290))        print &#39;exict&#39;
        sleep(2)
Copy after login
