Python List Append Syntax

The basic syntax of this function is:

 List.append(New_item)

This method will help us to add given item (New_item) at the end of the Old_list

Python Append List Function Example 1

First, we declared an integer list a with four integer values. Next code adds 50 to the end of List a

# Python Append List Items

a = [10, 20, 30, 40]

print("Original List Items are : ", a)
a.append(50)
print("List Items are          : ", a)

OUTPUT

Python Append List Function Example 2

In this program we are adding three integer values to an integer list using this list append function

# Python Append List Items

a = [10, 20, 30, 40]

print("Original List Items are : ", a)
a.append(50)
a.append(60)
a.append(70)
print("List Items are          : ", a)

Python List Append Function Example 4

This python program is same as first example. However, this time we are allowing user to enter the length of a List. Next, we used For Loop to append those numbers to the list.

# Python Append List Items

intList = []
 
number = int(input("Please enter the Total Number of List Elements: "))
for i in range(1, number + 1):
    value = int(input("Please enter the Value of %d Element : " %i))
    intList.append(value)
    
item = int(input("Please enter the New Item to append : " ))
print("Original List Items are : ", intList)
intList.append(item)
print("New List Items are      : ", intList)

Python List Append Function Example 5

In this python program, we used append function to add words to a list

# Python Append List Items

strList = []
 
number = int(input("Please enter the Total Number of List Elements: "))
