Append Multiple items to List - Python Last Updated : 02 Dec, 2024 Summarize Comments Improve Suggest changes Share Like Article Like Report Appending items to a list in Python is an essential and common operation when working with different data structures. Sometimes, we need to add more than one item to a list at a time and in this article, we will explore the various ways to append multiple items to a list at the same time.Using extend() MethodThe extend() method is the most straightforward way to append multiple items to a list at once. Python a = [1, 2, 3] # Extend the list with multiple items a.extend([4, 5, 6]) print(a) Output[1, 2, 3, 4, 5, 6] extend() method takes an iterable(like a list, tuple, or set etc) and then adds each item from that particular iterable to the list.Let's Explore some other methods to append multiple items to a list at onceTable of ContentUsing List ConcatenationUsing List ComprehensionUsing append() method in a loopUsing + operatorAnother way to add multiple items to a list is by simply using the '+' operator. Python a = [1, 2, 3] # Concatenate lists to add new items a = a + [4, 5, 6] print(a) Output[1, 2, 3, 4, 5, 6] The '+' operator concatenates two lists, so we can create a new list with the items we want to add by simply adding the two lists.Using List ComprehensionList Comprehension can be used to generate a new list and add items dynamically to that list. Python a = [1, 2, 3] # List comprehension to append multiple items a += [x for x in range(4, 7)] print(a) We can use this method when we want to add elements based on a condition or when we want to transform the list before adding new items.Using append() method in a loopThe append() method is used to add a single item to the end of a list, however to append multiple items at once using the append() method, we can use it in a loop. Here's how: Python a = [1, 2, 3] b = [4, 5, 6] #Append multiple items one by one using a loop for item in b: a.append(item) print(a) Output[1, 2, 3, 4, 5, 6] Here we iterate over the items and call append() for each one, adding each element to the list one by one.

In this guide, we'll look at some common ways to add single or multiple items to a list using built-in methods and operators with simple examples:Add a Single Item Using append()append() method adds one item to the end of the li 3 min read Python List Extend vs Append Python, being a versatile and powerful programming language, provides multiple ways to manipulate lists. Two commonly used methods for adding elements to a list are extend and append. While both serve the purpose of adding elements, they differ in functionality and use cases. In this article, we'll 4 min read Python | Initializing multiple lists In real applications, we often have to work with multiple lists, and initialize them with empty lists hampers the readability of code. Hence a one-liner is required to perform this task in short so as to give a clear idea of the type and number of lists declared to be used. Method #1: Using loops We 4 min read Python - List of tuples to multiple lists Converting a list of tuples into multiple lists involves separating the tuple elements into individual lists. This can be achieved using methods like zip(), list comprehensions or loops, each offering a simple and efficient way to extract and organize the data.Using zip()zip() function is a concise 3 min read Python - Append Multitype Values in Dictionary There are cases where we may want to append multiple types of values, such as integers, strings or lists to a single dictionary key. For example, if we are creating a dictionary to store multiple types of data under the same key, such as user details (e.g., age, address, and hobbies), we need to han 2 min read Like
