Do you want to append list to list in Python ? If yes then you have come at the right place. In this post you will know how to append list to list in python using various examples.
It’s obvious that you must know what is a list. But to those who do not know, the list is a data structure that allows you to store multiple values in a single variable. The list is widely used by most of the coders. It allows you to manipulate the variable inside the list.
Now let’s know the various examples for appending a list to a list in Python. Just follow it for a deep understanding.
Suppose you want to append a new list to the existing list. Then you have to use the append() function. Here you will just pass the new list to the existing list as an argument.
Use the below lines of code to achieve it.
list1 = ["A","B","C"]
list2= ["D","E","F","G"]
list1.append(list2)
print(list1)Output
The above example completely appends the list to another list. But if you want to append only elements to the existing list then you will use the extend() function. It takes a list as an argument.
Run the below lines of code to achieve that.
list1 = ["A","B","C"]
list2= ["D","E","F","G"]
list1.extend(list2)
print(list1)Output
The third example to append a list to a list is the use of the + operator. The process is the same as an addition but instead of a particular number it will add the elements to the existing list.
Execute the below lines of code and see the output.
list1 = ["A","B","C"]
list2= ["D","E","F","G"]
final_list = list1+list2
print(final_list)Output
In this tutorial, you have learned how to append a list to a list in Python. You have also learned how to append all the elements to the existing list using the extend() function, plus operator and other approaches.
