Here you can see that the result is equivalent to append(): > musical_notes = This syntax is essentially assigning the list that contains the element as the last portion (end) of the list. There is also an interesting equivalence between the append() method and list slicing. ? Equivalence of Append and List Slicing > musical_notes.insert(len(musical_notes), "B")īut as you have seen, append() is much more concise and practical, so it's usually recommended to use it in this case. Here's an example that shows that the result of using insert with these arguments is equivalent to append(): > musical_notes =

This is an example of a call to append(): > musical_notes = ? Tip: The first element of the syntax (the list) is usually a variable that references a list. This element can be of any data type:īasically, any value that you can create in Python can be appended to a list. When we call a method, we use a dot after the list to indicate that we want to "modify" or "affect" that particular list.Īs you can see, the append() method only takes one argument, the element that you want to append. ? Tip: The dot is very important since append() is a method. This is the basic syntax that you need to use to call this method: ? Tip: To add a sequence of individual elements, you would need to use the extend() method. Here you can see the effect of append() graphically: With this method, you can add a single element to the end of a list. You will find examples of the use of append() applied to strings, integers, floats, booleans, lists, tuples, and dictionaries. How it can be equivalent to insert() and string slicing with the appropriate arguments.This is a powerful list method that you will definitely use in your Python projects. Hi! If you want to learn how to use the append() method, then this article is for you.
