Add Character String to List in Python (4 Examples)


This short tutorial will show you how to join a character string to a list in Python.

Here, you can take a quick look at the tutorial structure:

Let’s dive into it!


Create Sample List of Strings

First of all, we will create a sample list of strings, to which we will add a character string.

my_list = ['apple', 'banana', ' grapes', 'cherry', 'watermelon']
# ['apple', 'banana', ' grapes', 'cherry', 'watermelon']

The previous output shows that my_list is a list object that contains five strings. Let’s see how to add another string to my_list!


Example 1: Join Character String to List via append() Method

The append() method can be handy when adding a new element to a list. Consider the Python code below.

# ['apple', 'banana', ' grapes', 'cherry', 'watermelon', 'strawberry']

The above example shows how we use the append() method to add the string “strawberry” at the end of my_list. Finally, the updated list is printed, which includes “strawberry” as the sixth element.


Example 2: Join Character String to List via ‘+’ operator

In this example, we will use the ‘+’ operator to concatenate a character string to my_list. Take a look at the code below.

my_list = my_list + ["strawberry"]
# ['apple', 'banana', ' grapes', 'cherry', 'watermelon', 'strawberry']

Great! We have the character string “strawberry” in my_list.

Example 3: Join Character String to List via extend() Method

The extend() method is another alternative for extending the existing list with a new character.

# ['apple', 'banana', ' grapes', 'cherry', 'watermelon', 'strawberry']

Again, we obtain a satisfactory result!

Example 4: Join Character String to List via insert() Method

This last example shows how to insert a character string to a list using the insert() method and the len() function. See below.

my_list.insert(len(my_list), "strawberry")
# ['apple', 'banana', ' grapes', 'cherry', 'watermelon', 'strawberry']

As shown in this example, we have passed the length of my_list as the first and the “strawberry” string as the second argument to the insert() method, which has inserted the new string at the end of the list.
