How to add items to a python list without using append():
We can add items to a python list without using append. There are many ways to do that. In this post, we will learn a few different ways to add items to a list with examples.
Method 1: By using ’+‘:
This is the easiest way to add items to a list in python. Plus operator or + can be used to add items to a list. We can add another list to a given list. Let’s take a look at the below program:
given_list = [1, 2, 3, 4, 5]
new_list = given_list + [6, 7, 8]
print(new_list)Here, We are creating new_list by adding items to the given_list. It will print the below output:
[1, 2, 3, 4, 5, 6, 7, 8]Method 2: Using extend:
extend() is a method defined in python list which can be used to append a list to the end of a list. extend method modifies the original caller list and it returns None. Let’s take a look at the example below:
given_list = [1, 2, 3, 4, 5]
given_list.extend([6, 7, 8])
print(given_list)It will print the below output:
[1, 2, 3, 4, 5, 6, 7, 8]
Method 3: Using slicing:
slicing is another way to add one or more items to a list. For example, the below program adds the items to the start of the given list:
given_list = [1, 2, 3, 4, 5]
given_list[:0] = [6, 7, 8]
print(given_list)It will print the below output:
[6, 7, 8, 1, 2, 3, 4, 5]Similarly, the below script adds items to the end of the list:
given_list = [1, 2, 3, 4, 5]
size = len(given_list)
given_list[size:] = [6, 7, 8]
print(given_list)It will print:
[1, 2, 3, 4, 5, 6, 7, 8]You might also like:
