[' Programming ', ' Python ', ' World ', ' Delete ', ' Element '] 使用Numpy 模块的 delete() 方法 当元素的索引被明确提及时,方法delete() 可以从数组中删除该元素。为了使用方法delete(),数组应该转换为Numpy数组的形式。也可以使用该模块执行将普通数组转换为 numpy 数组。下面描述了 delete() 方法...
That also means that you can't delete an element or sort atuple. However, you could add new element to both list and tuple with the onlydifference that you will change id of the tuple by adding element(tuple是不可更改的数据类型,这也意味着你不能去删除tuple中的元素或者是对tuple进行排序,...

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:...
() is a special token and denotes empty tuple. In 3, as you might have already figured out, there's a missing comma after 5th element ("that") in the list. So by implicit string literal concatenation, >>> ten_words_list ['some', 'very', 'big', 'list', 'thatconsists', 'of'...
