Imagine I wanted to extract, or access, the first element of my list. 我要做的第一件事是键入列表的名称,然后我需要方括号。 The first thing for me to do is type the name of the list,then I need my square brackets. 现在请记住,在Python中,索引从零开始。 Now remember, in Python, indexe...
(element1, element2, ... , elementn) 从存储内容上看,元组可以存储整数、实数、字符串、列表、元组等任何类型的数据,并且在同一个元组中,元素的类型可以不同,在这个元组中,有多种类型的数据,包括整形、字符串、列表、元组。例如: ("test.com.cn",1,[2,'a'],("abc",3.0)) ...
You have seen that an element in a list can be any sort of object. That includes another list. A list can contain sublists, which in turn can contain sublists themselves, and so on to arbitrary depth.Consider this (admittedly contrived) example:...
