如何在python 3.3中将嵌套的列表列表转换为元组列表?
问题描述：
我正在尝试将嵌套列表列表转换为Python 3.3中的元组列表.但是，似乎我没有这样做的逻辑.
I am trying to convert a nested list of lists into a list of tuples in Python 3.3. However, it seems that I don't have the logic to do that.
输入内容如下:
>>> nested_lst = [['tom', 'cat'], ['jerry', 'mouse'], ['spark', 'dog']]
所需的输出应如下所示:
And the desired ouptput should look as exactly as follows:
nested_lst_of_tuples = [('tom', 'cat'), ('jerry', 'mouse'), ('spark', 'dog')]
答
只需使用列表理解:
nested_lst_of_tuples = [tuple(l) for l in nested_lst]
演示:
>>> nested_lst = [['tom', 'cat'], ['jerry', 'mouse'], ['spark', 'dog']]
>>> [tuple(l) for l in nested_lst]
[('tom', 'cat'), ('jerry', 'mouse'), ('spark', 'dog')]
