selenium provides function find_element_by_css_selector() locates first element based on provided css selector. (there's multi-item variant, find_elements_by_css_selector(), returns list of matching elements.)

text = driver.find_element_by_css_selector('.dbalisting.listing.lastlisting > td:nth-child(4) > span').text

css main way of styling html. css selectors how elements chosen different styling. these selector rules used other tools well-known way of selecting elements.

. indicates class. (there # ids, not used here; nothing element names, used td , span; , : or :: psuedo-selectors.) tells system want elements class.
