![]() ![]() For adding more elements to the end of a list, the extend() method is preferred. If you have a list where you want to add a single element, the append() method is the best and easiest. append() increases the size of list by 1 whereas extend() increases the size of the list by the number of elements in the iterable argument.append() adds all argument as a single element to the end of a list whereas extend() iterates over the argument and add each element of argument at the end of the list. Python List extend() Method Example : Python list extend() Method Creating a list list 1,2,3 for l in list: Iterating list print(l).append() takes single element as an argument whereas extend() doesn't take single element as an argument.Here are some basic difference between append() and extend() in Python: We can see in the final output that all these values are added to the end of the variable mylist as individual elements. Mylist.append( is also added to extend the list. Mylist.append(("apple", "banana", "cherry")) Example of append() in Python # Python program to explain append function ![]() This function adds a single or group of elements at the end of a list as a single object. Instead of adding each element one by one using the append() method, we can use the extend() method to add entire elements of the list at once to repeat them. Note: Both the function (append & extend) works with a number, strin, list, tuple, set, dict. > lst 1, 2, 3 > x 4, 5 > lst.extend(x) extend add all. Python offers methods such as append() and extend() for this.īoth append() & extends() functions are used for string manipulation, i.e. lst.extend(lst2) - add all the elements of lst2 on to the end of lst. In case you want to add elements to the end of a list or before a specified index. Using this operator you can add two or more lists into a new list. The easiest ways to add elements to a list is by using the concatenation operator +. If you have a list of elements in Python, there might be a need to add more elements to it.
