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 How to Append Objects in a List in Python The simplest way to append an object in a list using append() method. This method adds an object to the end of the list. Pythona = [1, 2, 3] #Using append method to add object at the end a.append(4) print(a) Output[1, 2, 3, 4] Let's look into various other methods to append object in any list are:Ta 2 min read Python - Append Multiple Lists at Once Our task is to merge multiple lists into a single list by appending all their elements. For example, if the input is a = [1, 2], b = [3, 4], and c = [5, 6], the output should be [1, 2, 3, 4, 5, 6].Using itertools.chain()itertools.chain() function from the itertools module is another way to combine l 4 min read Append Text or Lines to a File in Python Appending text or lines to a file is a common operation in programming, especially when you want to add new information to an existing file without overwriting its content. In Python, this task is made simple with built-in functions that allow you to open a file and append data to it.
