更新：如果要从汽车下拉列表中获取选项，可以使用以下方法：
def getallcarlist(): currentselection = driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlVoertuigType']") select = Select(currentselection) select.select_by_visible_text("Motoren") time.sleep(5) x = driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlBouwdag']") select = Select(x) select.select_by_visible_text("1") y = driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlBouwmaand']") select = Select(y) select.select_by_visible_text("1") z = driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlBouwjaar']") select = Select(z) select.select_by_visible_text("2017") time.sleep(5) car = driver.find_element_by_css_selector("#ctl00_cp_ucSearch_Manual_ddlMerk") carlist =[] for option in car.find_elements_by_tag_name('option'): carlist.append((option.text).enpre('utf8')) return carlist这是称呼它的方式
listcar= getallcarlist()for c in listcar: print c
