找到有'内蒙古开放大学'字样的标签页

统计待批改题目数量

subject_card_elements = driver.find_elements(By.CLASS_NAME, 'subject-card') not_marked_count = 0 for subject_card_element in subject_card_elements: not_marked_elements = subject_card_element.find_elements(By.CLASS_NAME, 'not-marked') not_marked_count += len(not_marked_elements) print('待批改题目数量：', not_marked_count, '个')

提取题目编号

for subject_card_element in subject_card_elements: number_elements = subject_card_element.find_elements(By.XPATH, '//span[@class="ng-binding ng-scope"]') for number_element in number_elements: number = number_element.text print('题目编号：', number)
