如何使用css选择器获取所有href并查找元素？

Question

我使用下面的代码，我想得到所有的元素中的Href不只是第一个Href，但当我使用它时，我只得到第一个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')])

html代码，我想收集它的链接，我想收集所有的css选择器的href，我需要一些东西，如添加单词全部在css选择器路径前的一个字母
