python - 将另一个列表的最后一个对象分配给新列表 - Python

Question

好的，在 Python 中我有列表:

flowers = ["rose", "bougainvillea", "yucca", "marigold", "daylilly", "lilley of the valley"]

现在，我只想将列表 flowers 的最后一个对象分配给一个名为 poisonous 的新列表。

我试过:

poisonous=flowers[-1]

然而，此语句使字符串而不是列表成为有毒的。

Answer 1

>>> poisonous=[flowers[-1],] #take the last element and put it in a list
>>> poisonous
['lilley of the valley']
>>> poisonous=flowers[-1] #take the last element, which is a string
>>> poisonous
'lilley of the valley'
>>> poisonous=flowers[-1:] #take a slice of the original list. The slice is also a list.
>>> poisonous
['lilley of the valley']
