Question

在一个小型python项目上工作，并且达到了令我难过的地步。

runners = ["Tom","Bob","Bill","Gary"]

runner_id = [123223,234345,356543,487334]

event_id = [11,12,13,14]

event_time = [12.30,13.00,14.00,16.00]

我有上面的数据，希望最终得到每个跑步者的字典，并将dict命名为跑步者名称。

结果如下：

Tom = {runner_id : 123223, event_id : 11, event_time : 12.30}

Bob = {runner_id : 234345, event_id : 12, event_time : 13.00}

Bill = {runner_id : 356543, event_id : 13, event_time : 14.00}

Gary = {runner_id : 487334, event_id : 14, event_time : 16.00}

难以理解如何将dict命名为我需要它，即作为原始列表之一的名称。

已阅读了大量帖子，但无法找到此特定问题的答案。

感谢所有有用的指示。

非常感谢。

Answer 1

您可以使用词典理解和zip功能：

runners = ["Tom","Bob","Bill","Gary"]
runner_id = [123223,234345,356543,487334]
event_id = [11,12,13,14]
event_time = [12.30,13.00,14.00,16.00]

print {name:{'runner_id' : i, 'event_id' : j, 'event_time' : k} for i,j,k,name in zip(runner_id,event_id,event_time,runners)}

结果：

{'Bob': {'event_id': 12, 'event_time': 13.0, 'runner_id': 234345}, 'Bill': {'event_id': 13, 'event_time': 14.0, 'runner_id': 356543}, 'Gary': {'event_id': 14, 'event_time': 16.0, 'runner_id': 487334}, 'Tom': {'event_id': 11, 'event_time': 12.3, 'runner_id': 123223}}

Answer 2

您必须使用跑步者名称作为较大词典的键

runner_dict = {}
for index, runner in enumerate(runners):
    runner_dict[runner] = {
        'runner_id'  : runner_id[index],
        'event_id'   : event_id[index],
        'event_time' : event_time[index]
    }

Answer 3

如果您有一个包含所有跑步者及其词典的字典，那就好多了。所以相反，你有这个：

runners = {
    "Tom" : {runner_id : 123223, event_id : 11, event_time : 12.30},
    "Bob" : {runner_id : 234345, event_id : 12, event_time : 13.00},
    "Bill" : {runner_id : 356543, event_id : 13, event_time : 14.00},
    "Gary" : {runner_id : 487334, event_id : 14, event_time : 16.00},
    }

Answer 4

如下

runners = ["Tom","Bob","Bill","Gary"]
runner_id = [123223,234345,356543,487334]
event_id = [11,12,13,14]
event_time = [12.30,13.00,14.00,16.00]

runners_dict = {}
for index, runner in enumerate(runners):
    runners_dict[runner] = {
        'runner_id' : runner_id[index],
        'event_id' : event_id[index],
        'event_time' : event_time[index]
    }

如果你想得到某些跑步者的话，那么

runners_dict['name']
