使用 selenium 进行网络抓取时，我没有获得时间价值

Question

我有这个代码来抓取oddsportal页面：

https://www.oddsportal.com/soccer/england/premier-league/

browser = webdriver.Chrome()
browser.get("https://www.oddsportal.com/soccer/england/premier-league/")

df= pd.read_html(browser.page_source, header=0)[0]

timeList = []
dateList = []
gameList = []
home_odds = []
draw_odds = []
away_odds = []

for row in df.itertuples():
    if not isinstance(row[1], str):
        continue
    elif ':' not in row[1]:
        date = row[1].split('-')[0]
        continue
    time = timeList.append(row[1])
    dateList.append(date)
    gameList.append(row[2])
    home_odds.append(row[4])
    draw_odds.append(row[5])
    away_odds.append(row[6])

result = pd.DataFrame({'date':dateList,
                       'time':time,
                       'game':gameList,
                       'Home':home_odds,
                       'Draw':draw_odds,
                       'Away':away_odds})

我得到的输出为：

    date           time    game                             Home    Draw    Away

我没有从 time 中获得任何价值

有人可以帮助我了解我是否遗漏了什么吗？我是否正确定义了 time？

Answer 1

timeList.append(row[1]) 不返回任何内容，因此 time 始终为 None。我怀疑你想要：

    time = row[1]
    timeList.append(time)

Answer 2

我认为这是一个简单的疏忽错误。您已将 time 函数的返回值分配给 list.append() 变量，即 None。

所以，而不是：

time = timeList.append(row[1])

只需调用该函数，就像您对以下函数所做的那样：

timeList.append(row[1])
