Python:如何从字典中打印某些值

Question

我有一本字典self.ticketDict1，看起来像这样。

2457 : {'origin': u'HW', 
'department': u'Kunde', 
'ticket-closed': True, 
'prio-events': [(datetime.datetime(2015, 4, 27, 16, 53, 55, 64183, tzinfo=<LocalTimezone "UTC+02:00" 2:00:00>), u'Wichtig')], 
'status-events': [(datetime.datetime(2015, 4, 27, 16, 53, 55, 64183, tzinfo=<LocalTimezone "UTC+02:00" 2:00:00>), u'new'), 
(datetime.datetime(2015, 5, 15, 16, 5, 0, 179351, tzinfo=<LocalTimezone "UTC+02:00" 2:00:00>), u'closed'), 
(datetime.datetime(2015, 5, 28, 13, 32, 47, 523975, tzinfo=<LocalTimezone "UTC+02:00" 2:00:00>), u'closed'), 
(datetime.datetime(2015, 6, 9, 16, 8, 16, 726823, tzinfo=<LocalTimezone "UTC+02:00" 2:00:00>), u'closed')]}

2458 : {'origin': u'HW', 
'department': u'Kunde', 
'ticket-closed': True, 
'prio-events': [(datetime.datetime(2015, 4, 27, 16, 53, 55, 77779, tzinfo=<LocalTimezone "UTC+02:00" 2:00:00>), u'Wichtig')], 
'status-events': [(datetime.datetime(2015, 4, 27, 16, 53, 55, 77779, tzinfo=<LocalTimezone "UTC+02:00" 2:00:00>), u'new'), 
(datetime.datetime(2015, 5, 15, 15, 12, 53, 29570, tzinfo=<LocalTimezone "UTC+02:00" 2:00:00>), u'closed')]}

2459 : {'origin': u'HW', 
'department': u'Kunde', 
'ticket-closed': True, 
'prio-events': [(datetime.datetime(2015, 4, 27, 16, 53, 55, 94126, tzinfo=<LocalTimezone "UTC+02:00" 2:00:00>), u'W\xfcnschenswert')], 
'status-events': [(datetime.datetime(2015, 4, 27, 16, 53, 55, 94126, tzinfo=<LocalTimezone "UTC+02:00" 2:00:00>), u'new'), 
(datetime.datetime(2015, 5, 11, 14, 47, 28, 916677, tzinfo=<LocalTimezone "UTC+02:00" 2:00:00>), u'closed')]}

现在我想打印从每个项目的第一个 status-events 值开始的所有日历周。

我试过这样:

for i in self.ticketDict1:
      print i['status-events'][0][0].isocalendar()[1]

但我总是收到此错误:

File "/media/sf_Projects/Ticketauswertung/Converting.py", line 86, in ConvertData
print i['status-events'][0][0].isocalendar()[1]
TypeError: 'int' object has no attribute '__getitem__'

编辑: 如果我这样打印我的字典:

for i in self.ticketDict1:
            print i, ' : ', self.ticketDict1[i]
            print '\n'

我得到这个结果:

2556  :  {'origin': u'HW', 'department': u'Intern', 'ticket-closed': False, 'prio-events': [(datetime.datetime(2015, 7, 27, 16, 30, 59, 547747, tzinfo=<LocalTimezone "CEST" 2:00:00>), u'Wichtig')], 'status-events': [(datetime.datetime(2015, 7, 27, 16, 30, 59, 547747, tzinfo=<LocalTimezone "CEST" 2:00:00>), u'new')]}


2557  :  {'origin': u'HW', 'department': u'Intern', 'ticket-closed': False, 'prio-events': [(datetime.datetime(2015, 7, 27, 16, 32, 37, 491657, tzinfo=<LocalTimezone "CEST" 2:00:00>), u'Wichtig')], 'status-events': [(datetime.datetime(2015, 7, 27, 16, 32, 37, 491657, tzinfo=<LocalTimezone "CEST" 2:00:00>), u'new')]}


2558  :  {'origin': u'HW', 'department': u'Intern', 'ticket-closed': False, 'prio-events': [(datetime.datetime(2015, 7, 27, 16, 33, 51, 29451, tzinfo=<LocalTimezone "CEST" 2:00:00>), u'Wichtig')], 'status-events': [(datetime.datetime(2015, 7, 27, 16, 33, 51, 29451, tzinfo=<LocalTimezone "CEST" 2:00:00>), u'new')]}

如你所见，我的字典没有任何问题。

Answer 1

以下内容对我来说效果很好:

>>> x = {'status-events': [(datetime.datetime(2015, 4, 27, 16, 53, 55, 64183, None), u'new'), 
(datetime.datetime(2015, 5, 15, 16, 5, 0, 179351, None), u'closed'), 
(datetime.datetime(2015, 5, 28, 13, 32, 47, 523975, None), u'closed'), 
(datetime.datetime(2015, 6, 9, 16, 8, 16, 726823, None), u'closed')]}
>>> x['status-events'][0][0].isocalendar()
(2015, 18, 1)
>>> x['status-events'][0][0].isocalendar()[1]
18

这是因为您正在循环遍历 self.TicketDict1，它将为您提供字典中的每个键。你想要的是这样的:

for i in self.TicketDict1['statusevents'].values():
    i[0][0].isocalendar()[1]

我不确定 2457 是什么(我假设缺少一个冒号，它应该显示 2457:)，所以您可能需要这样:

for i in self.TicketDict1[2457]['statusevents'].values():
    i[0][0].isocalendar()[1]

您还想使用dictionary.values()来获取值，而不是键。例如:

x = {1:'one', 2:'two'}

for i in x.values():
    print i

>>> one
>>> two

同时:

x = {1:'one', 2:'two'}

for i in x:
    print i

>>> 1
>>> 2

当您按照当前编写的方式循环代码时，您将获得 key 。该错误可能是由于尝试从字典中的某个键检索项目，例如。 2457['status-events'][0][0].isocalendar()[1] 将抛出错误。

注意:

x = {1:'one', 2:'two'}

for i in x:
    print i[1]
