谢谢你,QHarr,我知道如何使用这个特定的类访问其他类。允许我这样做的代码行如下:

#for description
description = [i.text for i in driver.find_elements(By.CSS_SELECTOR, "#search-items > .search-item .details > a > .row.pt-5.pb-sm-5 > .multilines-3.text-truncate-multilines.xs-single-col-8.col-12 > .font-weight-bold.text-dark")]
print(description)
