How to insert item at end of Python list [4 different ways]

by

In this Python tutorial, we will discuss, how to insert item at end of Python list. We will see 4 different ways to add item to end of list python.

A list of items will be used as examples throughout the course to focus on list insertion because the list insertion technique must be the same regardless of the type of data the list contains. Let us see different ways to insert item at end of Python list.

Insert Item At End of Python List

Here let us see 4 different ways to insert item at end of Python list.

Method 1: Insert Item At End of Python List using insert() function

Python’s insert() function for lists that inserts a specified element or item at a specified index. The syntax is given below.

list_name.insert(index, value)

If the specified index is greater than or equal to the length of the list, the insert is made at the end of the Python list.

Create a list of items that is the real GDP percentage of the top 4 states in the USA such as Tennessee = 8.6, New Hemsphire = 8.5, California = 7.8 and Nevada = 7.1 using the below code.

usa_st_gdp = [8.6, 8.5, 7.8, 7.1]
print(usa_st_gdp)

Now we want to add the real GDP percentage of the new state Indiana or it is going to the 5th state in the list, we will use the insert() method.

usa_st_gdp.insert(len(usa_st_gdp), 6.9)

Check the list using the below code.

print(usa_st_gdp)

Look in the output, how we have inserted the item which floats value at the end of the list in Python.

Method 2: Insert an item at end of a list in Python using append() function

Create a list of items that is the real GDP percentage of the top 4 states in the USA such as Tennessee = 8.6, New Hemsphire = 8.5, California = 7.8 and Nevada = 7.1 using the below code.

usa_st_gdp = [8.6, 8.5, 7.8, 7.1]
print(usa_st_gdp)

We will now use the append() method to add the real GDP % of the new state Indiana or the state that will become the fifth state in the list.

usa_st_gdp.append(6.9)

View the list using the below code.

print(usa_st_gdp)

Method-3: Insert an item at end of a list in Python using + and [] Operator

Create a list of items that is the real GDP percentage of the top 4 states in the USA such as Tennessee = 8.6, New Hemsphire = 8.5, California = 7.8 and Nevada = 7.1 using the below code.

usa_st_gdp = [8.6, 8.5, 7.8, 7.1]
print(usa_st_gdp)

We will now use the + and [] operators to add the real GDP % of the new state Indiana or the state that will become the fifth state in the list.

usa_st_gdp = usa_st_gdp + [6.9]

View the list using the below code.

print(usa_st_gdp)

Method 4: To insert an item at end of a list in Python, use slicing method

Create a list of items that is the real GDP percentage of the top 4 states in the USA such as Tennessee = 8.6, New Hemsphire = 8.5, California = 7.8 and Nevada = 7.1 using the below code.

usa_st_gdp = [8.6, 8.5, 7.8, 7.1]
print(usa_st_gdp)

Now use the slicing method to add the real GDP % of the new state Indiana or the state that will become the fifth state in the list.

usa_st_gdp[4:5] = [6.9]

Show the list using the below code.

print(usa_st_gdp)
