我正在尝试使用Python以编程方式从以下站点下载数据：https://health.wyo.gov/publichealth/infectious-disease-epidemiology-unit/disease/novel-coronavirus/covid-19-testing-data/
在Tableau视图的右下角，有3个按钮：共享，下载和全屏。单击下载后，将转到另一个弹出窗口。然后，我想选择Crosstab，然后将您带到另一个弹出窗口，在这里我要选择Positivity，最后是要提供csv的Download。
[从本质上讲，我已经设法浏览了一些iframe，但是由于按钮不包含ID /链接，因此我对单击的位置有些迷茫。
下面是一种方法的代码：
from selenium import webdriver
url = 'https://public.tableau.com/profile/melissa.taylor#!/vizhome/WyomingCOVID-19TestingDataDashboard/Dashboard1'
driver = webdriver.Chrome()
driver.get(url)
#elem = driver.switch_to.frame(driver.find_element_by_xpath('//iframe[contains(text(), "googletagmanager"]'))
try:
time.sleep(4)
iframe = driver.find_elements_by_tag_name('iframe')[0]
driver.switch_to.default_content()
driver.switch_to.frame(iframe)
driver.find_elements_by_tag_name('iframe')
#driver.find_element_by_id('download-ToolbarButton').click()
print(driver.page_source)
finally:
driver.quit()
下面是显示Tableau页面中三个按钮的HTML。
