Question

我有

list('327VUQ56156TX374');
['3', '2', '7', 'V', 'U', 'Q', '5', '6', '1', '5', '6', 'T', 'X', '3', '7', '4']

我希望得到像这样的数组关联，它的索引。[ 1=>'3',... 16=>'4' ]

任何人都可以告诉我，谢谢

Answer 1

dict(enumerate('327VUQ56156TX374'))

如果你想从1开始计数（并且有充分的理由:-)），你可以使用它（但它仅用于＆gt; = 2.6）

dict(enumerate('327VUQ56156TX374', start=1))

Answer 2

我认为枚举会做你想做的事：

>>> data = list('327VUQ56156TX374')
>>> [(i+1,d) for i,d in enumerate(data)]
[(1, '3'), (2, '2'), (3, '7'), (4, 'V'), (5, 'U'), (6, 'Q'), (7, '5'), (8, '6'), (9, '1'), (10, '5'), (11, '6'), (12, 'T'), (13, 'X'), (14, '3'), (15, '7'), (16, '4')]
>>> dict((i+1,d) for i,d in enumerate(data))
{1: '3', 2: '2', 3: '7', 4: 'V', 5: 'U', 6: 'Q', 7: '5', 8: '6', 9: '1', 10: '5', 11: '6', 12: 'T', 13: 'X', 14: '3', 15: '7', 16: '4'}

Answer 3

也许你指的是关联数组？（a.k.a. python中的字典）

In [4]: dict((n+1, l) for n, l in enumerate('327VUQ56156TX374'))
Out[4]: 
{1: '3',
 2: '2',
 3: '7',
 4: 'V',
 5: 'U',
 6: 'Q',
 7: '5',
 8: '6',
 9: '1',
 10: '5',
 11: '6',
 12: 'T',
 13: 'X',
 14: '3',
 15: '7',
 16: '4'}
