最近工作不忙，開始學習python&selenium，有很多理解模糊的地方，做下記錄，希望大神可以指導。

練習1：

小插曲1：執行代碼以后，發現baidu.html空的，執行多次發現原因，必須關閉python執行窗口；

小疑問1：目前不太清楚方法close_alert_and_get_its_text，switch_to_alert；

錯誤1：執行多次偶爾會報錯，還在琢磨：

error1: ft1.3: Traceback (most recent call last):File "C:\learn_python\á·?°\baidu.py", line 44, in test_baidu_logindriver.find_element_by_css_selector("#u1 > a[name=\"tj_login\"]").click()File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 376, in find_element_by_css_selectorreturn self.find_element(by=By.CSS_SELECTOR, value=css_selector)File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 664, in find_element{'using': by, 'value': value})['value']File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 175, in executeself.error_handler.check_response(response)File "C:\Python27\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 166, in check_responseraise exception_class(message, screen, stacktrace) NoSuchElementException: Message: Unable to find element with css selector == #u1 > a[name="tj_login"]error2: ft1.1: Traceback (most recent call last):File "C:\learn_python\á·?°\baidu.py", line 21, in test_baidu_setdriver.find_element_by_css_selector("#u1 > a[name=\"tj_settingicon\"]").click()File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 376, in find_element_by_css_selectorreturn self.find_element(by=By.CSS_SELECTOR, value=css_selector)File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 664, in find_element{'using': by, 'value': value})['value']File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 175, in executeself.error_handler.check_response(response)File "C:\Python27\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 166, in check_responseraise exception_class(message, screen, stacktrace) NoSuchElementException: Message: Unable to find element with css selector == #u1 > a[name="tj_settingicon"]
