Chapter 8: Liste - Python

Una lista è una serie ordinata di valori, ognuno identificato da un indice. I valori che fanno parte della lista sono chiamati elementi. Le liste sono simili alle stringhe essendo insiemi ordinati di caratteri, fatta eccezione per il fatto che gli elementi di una lista possono essere di tipo qualsiasi.

What does [:-1] mean/do in python? - Stack Overflow

Example below using a list: It slices the sequence - it just might happen to be a list. It gets all the elements from the list (or characters from a string) but the last element. This is written ambiguously enough to be confusing. It's all of the elements up to but not including the last element.

Python Lists - W3Schools

Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are Tuple, Set, and Dictionary, all with different qualities and usage. Lists are created using square brackets: Create a List: List items are ordered, changeable, and allow duplicate values.

When using square brackets, one specifies either multiple items or a single item in the list. Whenever a programmer defines [::-1], it suggests that the program has to traverse from start to end in a given list. You can do indexing in python, which helps to slice and dice an iterable sequence such as a list or string. What is [::-1] in Python?

Python Lists - GeeksforGeeks

In Python, a list is a built-in dynamic sized array (automatically grows and shrinks). We can store all types of items (including another list) in a list. A list may contain mixed type of items, this is possible because a list mainly stores references at contiguous locations and actual items maybe stored at different locations.

Negative Indexing in Python List – How to Use “-1” Parameter

We have a built-in function reverse () in Python to reverse a list, let’s take a look. Example: Output: Here comes another option: we can use [::-1] to reverse a list without using the reverse () method. Example: Output: Using the pop () function while passing -1 as an argument inside it will remove the last element of that list. Example: Output:

In Python, the rightmost element of a list has ‘-1’ as the index and it reduces as we move to the left. The figure below depicts this. Example of accessing an element of a list: Output: We can also check the type of one of the elements using the index. Example of checking the type of accessed element: Output:

Here are all of the methods of list objects: Add an item to the end of the list. Similar to a[len(a):] = [x]. Extend the list by appending all the items from the iterable. Similar to a[len(a):] = iterable. Insert an item at a given position.

Python List: How To Create, Sort, Append, Remove, And More

Lists contain regular Python objects, separated by commas and surrounded by brackets. The elements in a list can have any data type and can be mixed. You can even create a list of lists. The following lists are all valid: Python lists, like all Python data types, are objects. The list class is called ‘list’, and it has a lowercase L.

list - what does [::-1] mean in python - slicing? - Stack Overflow

It will give you a new list b where the elements are in reverse order of a. If a=[0,1,2,3,4], b=[4,3,2,1,0] regardless of what a is, [::-1] reverses its order. It goes from end to start in steps of one, i.e. reverses the list. @Ev.Kounis no, only if __getitem__ works like the one from lists.
