我如何用python删除所有日期

Question

我需要刮soccerway.com我有问题，当我选择日期，例如2011-2013，进入比赛的每个环节，但问题只保存最后一个日期2012-2013，而不是2011-2012和2012-2013，但只有最后一个日期。你知道吗

def innerhtml_soup(driver):

    html = driver.find_element_by_tag_name("html").get_attribute("innerHTML")
    soup = BeautifulSoup(html, "html.parser")
    return soup

我要把2011-2013年的所有日期都删掉 2011-2012 2012-2013不仅仅是最后一天 我也找不出原因。你知道吗

Answer 1

如果我正确理解了代码，问题就出在这里：

url_list = cycle_through_game_weeks(driver)

在每次迭代中，您都要用新的url\u列表覆盖旧的url\u列表，最简单的解决方案是：

url_list += cycle_through_game_weeks(driver)

更加优雅有效：

   url_list = []
   while int(startdate)< int(enddate):
        textstring=str(startdate) + "/" + str(int(startdate)+1)
        print(textstring)
        driver.find_element_by_xpath("//select[@name='season_id']/option[text()='" + textstring +"']").click()
        startdate=int(startdate)+1
        url_list.append(cycle_through_game_weeks(driver))
   return url_list

这样，在url\u list[0]下，您将获得第一年的值，在url\u list[1]下的值，以此类推
