Explain the difference between "append()" and "extend()" methods in Python lists.

Question

Aryan Kumar · Answer

Sure. The append() and extend() methods are both used to add elements to a list in Python. However, they work in slightly different ways.
The append() method adds a single element to the end of a list. For example, the following code adds the number 5 to the end of the list
list1:
Python
list1 = [1, 2, 3]
list1.append(5)
print(list1)
This will print the list [1, 2, 3, 5].
The extend() method adds the elements of an iterable to the end of a list. For example, the following code adds the numbers 6, 7, and 8 to the end of the list
list1:
Python
list1 = [1, 2, 3]
list1.extend([6, 7, 8])
print(list1)
This will print the list [1, 2, 3, 6, 7, 8].
The main difference between the append() and extend() methods is that the
append() method only adds a single element to the end of a list, while the
extend() method can add multiple elements to the end of a list.
Here is a table that summarizes the differences between the append() and
extend() methods:
