A negative index of a list in Python refers to accessing elements in a list by counting from the end of the list rather than from the beginning. You can use negative indexing to access elements of a list or string from the end instead of the beginning. The index-1refers to the last e...
字符串是python当中最常用的数据类型,我们用它来处理文本内容,字符串是字符的有序集合,可以使用一对单引号或一对双引号,或者3对双引号来创建。Python 字符串负索引(Negative Indexing)。 Python 常用术语 1、负索引(Negative Indexing) 例如: 从索引5到索引1获取字符,从字符串末尾开始计数: b = "Hello, World!

In https://lectures.scientific-python.org/intro/language/basic_types.html#lists it is mentioned that all slicing parameters are optional. And a few examples are shown to demonstrate what values are implicitly set when you skip these. How...
Note that this is not advanced indexing (as the label says now), simple Python lists and tuples support it as well: >>>l=[1,2,3,4,5]>>>l[::-2] [5,3,1]>>>x=np.arange(5)>>>x[::-2]array([4,2,0])>>>t=torch.arange(5)>>>t[::-2] ...
