python - 查询 mongodb 引发停止迭代错误

Question

使用以下代码，我试图从 mongodb 中的对象中提取两个日期，然后计算两个日期之间的时间差——如果这两年都在 2016 年/过去。我当前的代码引发以下错误：

弃用警告：生成器 'QuerySet._iter_results' 从 ipykernel import kernelapp as app 引发了 StopIteration

我的代码： raw_data = Document.objects()

data = []
for i in raw_data[:10]:
    scored = i.date_scored
    scored_date =  pd.to_datetime(scored, format='%Y-%m-%d %H:%M')
    if scored_date == "NoneType":
        print("none")
    elif scored_date.year >= 2016:
        extracted = i.date_extracted
        extracted_date =  pd.to_datetime(extracted, format='%Y-%m-%d 
        %H:%M')
        bank = i.bank.name
        diff = scored_date - extracted_date
        print(diff)
        datum = [str(bank), str(extracted), str(scored), str(diff)]
        data.append(datum)
    else:
        pass

任何帮助将不胜感激，谢谢！
