复杂的数据结构联合

Question

我有以下表格的两个清单：

lst1 = [{u'Hours': [{u'HourOfDay': 15, u'TotalVisits': 1, u'TotalTimeSpent': 7223.0}, {u'HourOfDay': 11, u'TotalVisits': 1, u'TotalTimeSpent': 4503.0}, {u'HourOfDay': 18, u'TotalVisits': 1, u'TotalTimeSpent': 6273.0}, {u'HourOfDay': 12, u'TotalVisits': 3, u'TotalTimeSpent': 37550.0}], u'DayOfWeek': 1}, {u'Hours': [{u'HourOfDay': 9, u'TotalVisits': 50, u'TotalTimeSpent': 0.0}, {u'HourOfDay': 19, u'TotalVisits': 1, u'TotalTimeSpent': 7925.0}, {u'HourOfDay': 14, u'TotalVisits': 1, u'TotalTimeSpent': 4873.0}, {u'HourOfDay': 0, u'TotalVisits': 5, u'TotalTimeSpent': 10210.0}, {u'HourOfDay': 11, u'TotalVisits': 4, u'TotalTimeSpent': 21825.0}, {u'HourOfDay': 8, u'TotalVisits': 19, u'TotalTimeSpent': 0.0}, {u'HourOfDay': 9, u'TotalVisits': 8, u'TotalTimeSpent': 13055.0}, {u'HourOfDay': 16, u'TotalVisits': 1, u'TotalTimeSpent': 2816.0}, {u'HourOfDay': 11, u'TotalVisits': 2, u'TotalTimeSpent': 15723.0}, {u'HourOfDay': 13, u'TotalVisits': 9, u'TotalTimeSpent': 30987.0}, {u'HourOfDay': 10, u'TotalVisits': 11, u'TotalTimeSpent': 68384.0}, {u'HourOfDay': 15, u'TotalVisits': 26, u'TotalTimeSpent': 62650.0}, {u'HourOfDay': 12, u'TotalVisits': 3, u'TotalTimeSpent': 8626.0}, {u'HourOfDay': 17, u'TotalVisits': 2, u'TotalTimeSpent': 34456.0}, {u'HourOfDay': 16, u'TotalVisits': 5, u'TotalTimeSpent': 6915.0}, {u'HourOfDay': 15, u'TotalVisits': 5, u'TotalTimeSpent': 3151.0}, {u'HourOfDay': 3, u'TotalVisits': 8, u'TotalTimeSpent': 54720.0}, {u'HourOfDay': 19, u'TotalVisits': 6, u'TotalTimeSpent': 23497.0}], u'DayOfWeek': 2}, {u'Hours': [{u'HourOfDay': 11, u'TotalVisits': 56, u'TotalTimeSpent': 0.0}, {u'HourOfDay': 8, u'TotalVisits': 1, u'TotalTimeSpent': 4418.0}, {u'HourOfDay': 11, u'TotalVisits': 4, u'TotalTimeSpent': 9952.0}, {u'HourOfDay': 9, u'TotalVisits': 5, u'TotalTimeSpent': 12678.0}, {u'HourOfDay': 10, u'TotalVisits': 11, u'TotalTimeSpent': 89911.0}, {u'HourOfDay': 22, u'TotalVisits': 2, u'TotalTimeSpent': 0.0}, {u'HourOfDay': 14, u'TotalVisits': 1, u'TotalTimeSpent': 1593.0}, {u'HourOfDay': 12, u'TotalVisits': 10, u'TotalTimeSpent': 36453.0}], u'DayOfWeek': 3}, {u'Hours': [{u'HourOfDay': 13, u'TotalVisits': 22, u'TotalTimeSpent': 0.0}, {u'HourOfDay': 13, u'TotalVisits': 3, u'TotalTimeSpent': 4800.0}, {u'HourOfDay': 12, u'TotalVisits': 1, u'TotalTimeSpent': 212.0}, {u'HourOfDay': 10, u'TotalVisits': 4, u'TotalTimeSpent': 13503.0}, {u'HourOfDay': 14, u'TotalVisits': 7, u'TotalTimeSpent': 19533.0}, {u'HourOfDay': 11, u'TotalVisits': 5, u'TotalTimeSpent': 17512.0}, {u'HourOfDay': 22, u'TotalVisits': 14, u'TotalTimeSpent': 0.0}, {u'HourOfDay': 16, u'TotalVisits': 1, u'TotalTimeSpent': 6121.0}, {u'HourOfDay': 9, u'TotalVisits': 1, u'TotalTimeSpent': 5455.0}, {u'HourOfDay': 15, u'TotalVisits': 7, u'TotalTimeSpent': 21476.0}], u'DayOfWeek': 4}, {u'Hours': [{u'HourOfDay': 15, u'TotalVisits': 4, u'TotalTimeSpent': 12697.0}, {u'HourOfDay': 11, u'TotalVisits': 4, u'TotalTimeSpent': 10656.0}, {u'HourOfDay': 9, u'TotalVisits': 5, u'TotalTimeSpent': 11879.0}, {u'HourOfDay': 8, u'TotalVisits': 1, u'TotalTimeSpent': 924.0}, {u'HourOfDay': 19, u'TotalVisits': 1, u'TotalTimeSpent': 8075.0}, {u'HourOfDay': 10, u'TotalVisits': 20, u'TotalTimeSpent': 15478.0}, {u'HourOfDay': 12, u'TotalVisits': 6, u'TotalTimeSpent': 24608.0}, {u'HourOfDay': 14, u'TotalVisits': 8, u'TotalTimeSpent': 12858.0}, {u'HourOfDay': 13, u'TotalVisits': 1, u'TotalTimeSpent': 2545.0}], u'DayOfWeek': 5}, {u'Hours': [{u'HourOfDay': 19, u'TotalVisits': 1, u'TotalTimeSpent': 426.0}, {u'HourOfDay': 14, u'TotalVisits': 1, u'TotalTimeSpent': 1528.0}, {u'HourOfDay': 12, u'TotalVisits': 4, u'TotalTimeSpent': 11558.0}, {u'HourOfDay': 4, u'TotalVisits': 4, u'TotalTimeSpent': 0.0}, {u'HourOfDay': 16, u'TotalVisits': 1, u'TotalTimeSpent': 771.0}, {u'HourOfDay': 13, u'TotalVisits': 4, u'TotalTimeSpent': 2449.0}, {u'HourOfDay': 15, u'TotalVisits': 17, u'TotalTimeSpent': 67983.0}, {u'HourOfDay': 11, u'TotalVisits': 5, u'TotalTimeSpent': 1452.0}, {u'HourOfDay': 10, u'TotalVisits': 3, u'TotalTimeSpent': 5075.0}, {u'HourOfDay': 8, u'TotalVisits': 3, u'TotalTimeSpent': 4769.0}, {u'HourOfDay': 9, u'TotalVisits': 14, u'TotalTimeSpent': 49453.0}, {u'HourOfDay': 10, u'TotalVisits': 1, u'TotalTimeSpent': 0.0}], u'DayOfWeek': 6}, {u'Hours': [{u'HourOfDay': 17, u'TotalVisits': 8, u'TotalTimeSpent': 0.0}], u'DayOfWeek': 7}]

我想添加在这两个列表中花费的总时间并创建一个新列表，即如果同一DayOfWeek的HourOfDay相同，则添加TotalTimeSpent否则将信息附加到Hours列表。

我试过这个，但它没有运行！

for item1, item2 in zip(lst1,lst2):
    for hr1 in item1["Hours"]:
        for hr2 in item2["Hours"]:
            if hr1["HourOfDay"] == hr2["HourOfDay"]:
                hr1["TotalTimeSpent"] = hr1["TotalTimeSpent"] + hr2["TotalTimeSpent"]
            else:
                item1["Hours"].append(hr2)  

我想要的是每天两个列表的并集，如果同一天的两个集合的HourOfDay字段相同，则添加totalvisits和totaltimespent。

Answer 1

我没有足够的代表发表评论，所以我会在这里写下我的疑虑。

首先，我猜测第二个for循环中缺少的缩进级别是一个拼写错误，并且它没有出现在原始代码中。

其次，我不理解你的其他陈述的含义。

从本质上讲，你所做的是创造一个无限循环。

这意味着您的代码，在第一个列表的每个小时内，您扫描第二个列表以查找匹配项。

如果找到匹配项，则更新hr1（不管它基本上是一个“光标”这样的事实，所以一旦离开循环就会变得相当无用），否则你将一个元素附加到结尾处原始列表？

请记住，您正在扫描原始列表，而不是副本。

我快速写了这段代码，试一试让我知道：

final = lst1[::]
broken = False
i = j = 0
for item1, item2 in zip(lst1,lst2):
    # Backup copy
    it2_hrs = item2["Hours"]
    # Scan first list
    for hr1 in item1["Hours"]:
        # Scan second list
        for index,hr2 in enumerate(item2["Hours"]):
            print "index: {0} ;; hr2: {1}".format(index,hr2)
            if hr1["HourOfDay"] == hr2["HourOfDay"]:
                final[i]["Hours"][j]["TotalTimeSpent"] = hr1["TotalTimeSpent"] + hr2["TotalTimeSpent"]
                it2_hrs.pop(index)
                j += 1
                broken = True
                break
        if broken == True:
            broken = False
            continue
    final[i]["Hours"].extend(it2_hrs)
    i += 1
    j = 0
    break

print final
