标题: 运行python 脚本报错
新手刚接触python。现在运行python 脚本报错，请问如何定位或debug python 脚本在哪一步时候报错。 Message后面的信息是空的，很奇怪

看起来像是没得到页面的相应值，你把代码都贴上来看看

总感觉 self.browser.implicitly_wait(60) 一直没起作用。去掉注释time.sleep(10)，又可以往下跑

报错说Message: Unable to locate element: [id="acct"]

你把这个@array=Select(self.browser.find_element_by_id('acct')),然后print(@array)，看看下拉菜单中的值是否获取到了。

我在py2.7中这样用的，2.7需要转码utf-8和gbk互相转换。

dropdown = Select(driver.find_element_by_tag_name("select")).options

for tmp in dropdown:
select.select_by_visible_text(tmp.text.encode('utf-8'))

我在有执行click()动作的行后注释掉self.browser.implicitly_wait(60) ，加上time.sleep() 就可以了。但是time.sleep()不智能等待影响执行效率。self.browser.implicitly_wait(60) 是隐式智能等待为什么在这里没有起到相应作用？

def login(self):

      try:
         id = self.wait.until(EC.presence_of_element_located((By.ID, 'loginName')))
         id.send_keys(self.username)
         password = self.wait.until(EC.presence_of_element_located((By.ID, 'password')))
         password.send_keys(self.pwd)
      except TimeoutError:
         auto_cirats()

      self.browser.implicitly_wait(60)
      submit = self.browser.find_element_by_name('button_okButton')
      submit.click()
      time.sleep(12)
      self.apars()

def apars(self):

      if self.inner_count >= 3:
         print('Retry to the limited times, quit.')
         self.browser.quit()
      else:
         self.inner_count += 1
         try:
#             apar_menu = self.wait.until(EC.presence_of_element_located((By.ID, 'ibm-primary-links')))
            self.browser.implicitly_wait(60)
            patch_advisory = self.browser.find_element_by_xpath('//*[@id="ibm-primary-links"]/li[3]/a')
            patch_advisory.click()
#             button = apar_menu.find_element_by_xpath('//*[@id="ibm-primary-links"]/li[3]/a')
#             button.click()

         Select(self.browser.find_element_by_id('acct')).select_by_visible_text(self.account)
         self.browser.find_element_by_xpath('//*[@id="MainForm"]/table/tbody/tr/td/table/tbody/tr/td/table/tbody/tr[13]/td/div/div[2]/div/input[1]').click()
         time.sleep(7)

你说的self.browser.implicitly_wait(60)我没试过，

试试这个呢，self.browser..manage().timeouts().implicitlyWait(120, TimeUnit.SECONDS); 这个貌似等到timeout。
