If you’re new to programming in Python, you may be wondering what the term “append” means. In short, “append” is a built-in function that allows you to add new items to the end of a list.
In this article, we’ll take a closer look at how the append function works and how you can use it in your own Python programs.

Introduction
When you come across the append() method in Python, you might wonder what it does. Simply put, the append() method allows you to add an item to the end of a list. For example, if you had a list of animals, you could use the append() method to add another animal to the end of the list.
In this article, we’ll take a closer look at the append() method and show you how to use it in your Python code.
What is Append?
Append is a method in Python that is used to add an element to the end of a list.
Append Function in Python
The append function in python is used to add a new element to the end of a list. It takes one argument, which is the element to be added. For example:
>>> my_list = [1, 2, 3]
>>> my_list.append(4)
>>> my_list
[1, 2, 3, 4]
Difference between Append and Extend
The main difference between append and extend is that append adds the given element to the end of the list while extend adds the given element to the end of the list and extends it.
How to use Append?
Append is used to add elements at the end of the list.
The syntax of append is:
list.append(element)
append() Parameters
The append() method takes a single element as an argument.
Returns
The append() method returns the updated list.
Append method for lists
The append method for lists in Python is used to add an item to the end of a list. The item can be any data type, including another list. The append method does not return a value; it simply modifies the list in place.
Lists are mutable, meaning they can be modified in place. The append method is one of many ways to do this. Other methods include pop, which removes an item from the end of a list, and insert, which inserts an item at a given index.
To use the append method, you must first create a list. This can be done using the square brackets ([ and ]). For example:
my_list = [1,2,3]
my_list.append(4)
print(my_list)
# Output: [1, 2, 3, 4]
Append function for strings
The append function is used to add a new element to the end of a list. It takes one argument, the element to be added. For example:
list = [1,2,3]
list.append(4)
print(list)
This would print [1,2,3,4].
Append function for tuples
The append function is a built-in function in Python that takes a single element and adds it to the end of a tuple. The element can be of any type, including another tuple. If you are appending a tuple to another tuple, make sure to add extra parentheses around the added tuple so that it is clear that it is a unit. For example, if you have a list [(1,2),(3,4)] and you want to append the element (5,6) to it, you would write [(1,2),(3,4),((5,6))].If you are adding more than one element at a time, use the extend function instead of append.
Append function for dictionaries
The append function is used to add items to the end of a dictionary in Python. It takes two arguments, the key and the value, and adds them to the dictionary. If the key already exists in the dictionary, then the value is updated.
Conclusion
Appending is when you add an element to the end of a list. This is the most common way to add elements to a list. You can append an element to a list using the append() method.
