TypeError: sequence index must be integer, not 'slice' The TypeError shows that a deque can only be indexed using an integer, and a slice can’t be used in the square brackets. Deques are optimized to provide efficient access at either the beginning or the end of the data structure. The...
在a2t函式中,根據size_t整數類資料類型,index_sequence是integer_sequence的別名。make_index_sequence是編譯時期的別名,會以呼叫端傳入之陣列相同的項目數,建立以零為起始的index_sequence。a2t會將index_sequence以值傳遞至a2t_,其中運算式a[I]...會解除封裝I,然後項目會饋送至make_tuple,它會使用它們做為個別...
1、sequence是定义了__getitem__()和__len__()函数的可迭代对象,内置序列有list、str、tuple、bytes,dict虽然也实现了__getitem__()和__len__()函数,但它是映射类型。 2、抽象基类collections.abc.Sequence中定义了许多接口如count(), index(), __contains__(), and __reversed__()可用于扩展。 coll...

It shows how to use an integer_sequence to create a std::tuple from a std::array<T,N>, and how to use an integer_sequence to get at the tuple members.In the a2t function, an index_sequence is an alias of integer_sequence based on the size_t integral type. make_index_sequence ...
在print_tuple函数中,我们使用std::make_index_sequence来生成一个std::index_sequence,然后将其传递给print_tuple_impl函数。 在口语交流中,我们可以这样描述这个示例: “In this example, we first define a helper functionprint_tuple_implthat takes astd::tupleand astd::index_sequenceas parameters. Then, ...
