            f.write('\n')
        r=r+1

    driver.close()

会输出到D盘根目录下的test.txt文本中

用不了，报
AttributeError: 'WebDriver' object has no attribute 'find_element_by_xpath'

你没有根据你的浏览器版本来安装对应插件  这个是edge的，另外修改为
driver.find_element_by_xpath("/html/body/form/div[5]/input").click()#点击按钮
为
driver.find_element(By.XPATH,"/html/body/form/div[5]/input").click()#点击按钮
语法修改了
