A full description of the supported specifiers could be discovered within the Model specifier specification. Under are some examples. This example shows how to use destructive numbers to entry components from the record starting from the top. Detrimental indexing makes it simple to get objects with out needing to know the precise size of the listing. In this example, we’ll reverse your complete list using a slicing trick. By using a unfavorable step worth, we are able to move by means of the list in reverse order. Explanation: The unfavourable step (-1) signifies that Python ought to traverse the checklist in reverse order, beginning from the top. ] begins from the end of the record and strikes to the beginning which lead to reversing checklist.
