This method adds an object to the end of the list. Python a = [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:Table of ContentUsing extend() MethodUsing += OperatorUsing List ComprehensionUsing extend() MethodIf we want to add each item from one list to another, we can use the extend() method. This method adds each element from the second list to the first list individually. Python a = [1, 2, 3] # list 'a' by adding elements from the list a.extend([4, 5]) print(a) Output[1, 2, 3, 4, 5] Using += OperatorAnother way to append items from one list to another is by using the += operator. This works like extend() and adds each element of the second list to the first. Python a = [1, 2, 3] b = [4, 5] #Using += operator to add element a += b print(a) Output[1, 2, 3, 4, 5] Using List ComprehensionList comprehension is a shorter way to append objects while performing some operation on them. It is useful when we want to create a new list based on an existing one. Python a = [1, 2, 3] #Using list comphrehension #Adds [3, 4] to the end of 'a' a += [x + 3 for x in range(2)] print(a) Output[1, 2, 3, 3, 4] Comment More infoAdvertise with us Next Article How to Append Objects in a List in Python P pragya22r4 Follow Improve Article Tags : Python Python Programs python-list Python list-programs Practice Tags : pythonpython-list Similar Reads How to Append Multiple Items to a List in Python Appending multiple items to a list in Python can be achieved using several methods, depending on whether you want to extend the list with individual elements or nested collections.
