# 连接浏览器实例
driver = webdriver.Chrome(options=options)

# 在该浏览器查找标签页名称为'国家开放大学个人空间'
target_title = '国家开放大学个人空间'
for handle in driver.window_handles:

# 在网页中查找class属性为<p class='learning_course'> Android智能手机编程# </p>并点击
wait = WebDriverWait(driver, 10)
element = wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'p.learning_course')))
element.click()
