如何转换包含单个字符串且字符串中包含多个条目的列表。 Python 3

Question

Let's say you have a list, which contains a single string as: 假设您有一个列表，其中包含一个字符串，如下所示：

listExample = ['cat, dog, mouse, elephant']

So printing this list return the values as a single string: 因此，打印此列表将值作为单个字符串返回：

>>>'cat, dog, mouse, elephant'

How do you get this string to the point where you can get the entries as multiple strings, such as: 如何使此字符串达到可以将条目作为多个字符串获取的地步，例如：

>>>print(anotherList)
>>>['cat', 'dog', 'mouse', 'elephant']

Answer 1

You are describing the basic usage of str.split : 您正在描述str.split的基本用法：

>>> listExample = ['cat, dog, mouse, elephant']
>>> listExample[0].split(', ')
['cat', 'dog', 'mouse', 'elephant']

Answer 2

You should use the split method. 您应该使用split方法。 So do 也是

'cat, dog, mouse, elephant'.split(', ')

this will give you 这会给你

['cat', 'dog', 'mouse', 'elephant']

The ', ' means the string should be split every time there is a comma and then a space. ', '表示字符串应在每次出现逗号和空格后分开。

The list is not needed, but if you absolutely have to use the list then do 该列表不是必需的，但是如果您绝对必须使用该列表，请执行

listExample[0].split(', ')

to get the string out of the list and then split it. 从列表中取出字符串，然后将其拆分。
