一、场景回溯：环境：夜神模拟器+Appium+Python打开Pycharm，直接执行脚本：# coding:utf-8
from appium import webdriver
# desired_caps = {}
desired_caps = dict()
desired_caps['platformName'] = "Android"
# 声明是ios还是Android系统
desired_caps['platformVersion'] = '5.1.1'
# Android内核版本号，可以在夜神模拟器设置中查看
desired_caps['deviceName'] = '127.0.0.1:62001'
# 连接的设备名称
desired_caps['appname'] = 'kaoyan3.1.0.apk'
desired_caps['noReset'] = 'False'
desired_caps['unicodeKeyboard'] = 'True'
desired_caps['resetKeyboard'] = 'True'
desired_caps['appPackage'] = 'com.tal.kaoyan'
# apk的包名
desired_caps['appActivity'] = 'com.tal.kaoyan.ui.activity.SplashActivity'
# apk的launcherActivity
driver = webdriver.Remote('
}

Anaconda的JupyterLab 作为优秀的网页编辑器，非常适用于编写Python程序，但往往可能因一些原因如
JupyterLab报错：Server Connection Error，而无法正常连接服务器，为此我整理了以下方法，以解决该问题。
一、报错情形JupyterLab报错：Server Connection Error: A connection to the jupyter server could not be established. Jupyterlab will continue trying to reconnect. Check your network connection or jupyter server.服务器连接错误:jupyter服务器无法建立连接。木星实验室将继续尝试重新连接。检查您的网络连接或jupyter服务器。在此情况下，无法使用Python，无法进行编译，时常弹出错误，无法连接！二、深层原因使用微软账号登陆windows后，用户名称中存在中文名，导致jupyter路径中含有中文，无法识别路径。三、解决方案解决办法：（以Win10为例） 将用户名修改为英文，问题解决！以下介绍修改用户名的方式：3.1 重命名用户名右键【计算机】->【管理】->【本地用户和组】->【用户】->右键【中文用户名】->【重命名】3.2 启用Administrator账户Win10默认将Administrator账户禁用，在此需要启用Administrator账户，方法如下：在上步继续，右键【Administrator】->【属性】->取消勾选【账户已禁用】3.3 切换Administrator账户注销当前账户：【Windows+X】-【注销】重启电脑切换到Administrator账户登录3.4 重命名用户文件夹进入C:\用户\xxx，找到以中文用户名命名的文件夹，重命名为英文，不建议使用空格3.5 修改注册表打开Windows注册表管理器：【Windows+R】->【运行】->输入regedit依次展开HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Profilelist，在Profilelist下的文件夹对应系统中用户，而文件夹中ProfileImagePath值是指向每个用户文件夹的地址，一个个点击查看，找到中文名用户的对应所在的ProfileImagePath值修改ProfileImagePath的值，将地址改为修改成英文的文件夹名，要与C盘的文件夹名一致再次注销，完成登录用户文件夹名更改重新登录，以修改后用户名后的账户3.6 修改环境变量打开【控制面板】-【系统和安全】-【系统】-【高级系统设置】-【环境变量】将用户变量和系统变量中，所有含原用户名的字符修改为当前用户名打开Anaconda的JupyterLab，配置Python，连接成功，可以正常编辑解释代码，问题已解决！小结在创建Windows用户或新建文件夹时，习惯使用英文命名，将避免很多不必要的麻烦！}

我有一个问题：我想测试"select"和"input"。我能像下面的代码那样写吗：原始代码：12 class Sinaselecttest(unittest.TestCase):
13
14
def setUp(self):
15
binary = FirefoxBinary('/usr/local/firefox/firefox')
16
self.driver = webdriver.Firefox(firefox_binary=binary)
17
18
def test_select_in_sina(self):
19
driver = self.driver
20
driver.get("https://www.sina.com.cn/")
21
try:
22
WebDriverWait(driver,30).until(
23
ec.visibility_of_element_located((By.XPATH,"/html/body/div[9]/div/div[1]/form/div[3]/input"))
24
)
25
finally:
26
driver.quit()
# #测试select功能
27
select=Select(driver.find_element_by_xpath("//*[@id='slt_01']")).select_by_value("微博")
28
element=driver.find_element_by_xpath("/html/body/div[9]/div/div[1]/form/div[3]/input")
29
element.send_keys("杨幂")
30
driver.find_element_by_xpath("/html/body/div[9]/div/div[1]/form/input").click()
31
driver.implicitly_wait(5)
32
def tearDown(self):
33
self.driver.close()我想测试Selenium "选择" www.example.com我选择新浪网站选择一个选项，并在textarea中输入文本。然后搜索它。但当我运行此测试时，它有错误：function.so I choose sina website to select one option and input text in textarea.then search it .but when I run this test,it has error:Traceback (most recent call last):
