| append() | extend() |
|---|---|
| The append() method adds a single item to the end of the list. The single element can be list, number, strings, dictionary etc. | The extend() method adds one list at the end of another list. |
The syntax of append() method is list.append(item). | The syntax of extend() method is list.extend(list1). |
| For example: lst1 = [10, 12, 14] lst1.append(16) print(lst1) Output — [10, 12, 14, 16] | For example: t1 = ['a', 'b', 'c'] t2 = ['d', 'e'] t1.extend(t2) print(t1) Output — ['a', 'b', 'c', 'd', 'e'] |
