我正在使用下面的代码，我想获取元素中的所有Href不仅是第一个Href，而且当我使用它时，我只会得到第一个Href
communities = driver.find_elements_by_css_selector('div.coin-link-row:nth-child(4) > div:nth-child(2)>a')
sources = driver.find_elements_by_css_selector('div.coin-link-row:nth-child(5) > div:nth-child(2)>a')
with open('example2.csv', 'a') as myFile:
writer = csv.writer(myFile)
for community, source in zip(communities, sources):
writer.writerow([ community.get_attribute('href'), source.get_attribute('href')])
我想从中收集链接的html代码，我想通过css选择器收集所有href，我需要一些东西，例如在css选择器路径中的字母a之前全部添加单词
