我正在使用 Daniel Rodriguez 的稍微编辑过的代码。我正在尝试获取 2014 年以来的所有 NBA 盒子得分数据。此代码有两个先前部分:第一个获取所有球队名称,第二个获取具有 ESPN 比赛 ID、日期、主队的球队的所有比赛,主场比分,客场球队和客场比分。这两个部分工作得很好。
然后我尝试运行从游戏 ID 中获取游戏的所有 boxscore 数据的部分。它适用于大部分游戏,然后几乎随机停止游戏并给出错误:
AttributeError:“NoneType”对象没有属性“find_all”
我说随机是因为我一遍又一遍地运行相同的代码,并且它永远不会停止在相同的盒子分数上。它每次都会在不同的盒子分数上出错。
这是代码(**行是错误发生的地方):
