轉換元組在Python

Question

字典我有一個元組，如下所示：

(1, ['a', 'b', 'c']) 

我如何轉換這樣的元組爲以下詞典嗎？

{1: ['a', 'b', 'c’]}` 

我的實際元組看起來就像這樣：

a = (0, ['http://www.armslist.com/posts/2997703/pittsburgh-pennsylvania-handguns-for-sale--80--1911-frame', 'http://www.armslist.com/posts/4240186/racine-wisconsin-rifles-for-sale--stainless-winchester-m70-300wsm']) 

當我試圖將其轉換爲使用dict(a)它給了一個錯誤的字典：

TypeError: cannot convert dictionary update sequence element #0 to a sequence

我該如何解決它？

Answer 1

你可以通過元組的可迭代的dict：

In [22]: dict([(1,['a','b','c'])]) 
Out[22]: {1: ['a', 'b', 'c']} 

Answer 2

使用dict([a])

In[56]: a=(0, ['http://www.armslist.com/posts/2997703/pittsburgh-pennsylvania-handguns-for-sale--80--1911-frame', 'http://www.armslist.com/posts/4240186/racine-wisconsin-rifles-for-sale--stainless-winchester-m70-300wsm']) 
In[57]: dict([a]) 
Out[57]: 
{0: ['http://www.armslist.com/posts/2997703/pittsburgh-pennsylvania-handguns-for-sale--80--1911-frame', 
    'http://www.armslist.com/posts/4240186/racine-wisconsin-rifles-for-sale--stainless-winchester-m70-300wsm']}
