问题描述

我正在尝试将嵌套的列表列表转换为 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')]

解决方案

只需使用列表推导:

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')]
