Python append List is used to add an item to the end of an old list. This Python append list function help us to add given item (New_item) at the end of the existing Old_list The syntax of this append function is as shown below
list.append(New_item)
Python List append Function Example
First, we declared an integer list with four integer values. Next, the append code adds 50 to the end of List a
TIP: Please refer to the List and List functions articles in Python.
a = [10, 20, 30, 40]
print("Original Items are : ", a)
a.append(50)
print("New Items are : ", a)
Original Items are : [10, 20, 30, 40]
New Items are : [10, 20, 30, 40, 50]We are adding three integer values to an integer list using this list append function.
a = [10, 20, 30, 40]
print("Original Items are : ", a)
a.append(50)
a.append(60)
a.append(70)
print("New Items are : ", a)
Original Items are : [10, 20, 30, 40]
New Items are : [10, 20, 30, 40, 50, 60, 70]Python append List of Strings example
In this append example, we declared a string list. Next, we used the list append function to add another fruit to this list.
Fruits = ['Apple', 'Orange', 'Kiwi', 'Grape']
print("Original Items are : ", Fruits)
Fruits.append('Banana')
print("New Items are : ", Fruits)
Original Items are : ['Apple', 'Orange', 'Kiwi', 'Grape']
New Items are : ['Apple', 'Orange', 'Kiwi', 'Grape', 'Banana']This program is the same as the first list append example. However, we are allowing the user to enter the length of a List. Next, we used For Loop to append those numbers to the list.
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)
In this program, we used the list append method to add words.
strFruits = []
number = int(input("Please enter the Total Number of Elements: "))
for i in range(1, number + 1):
value = input("Please enter the Value of %d Element : " %i)
strFruits.append(value)
item = input("Please enter the New Item to append : " )
print("Original Items are : ", strFruits)
strFruits.append(item)
print("New Items are : ", strFruits)
Please enter the Total Number of Elements: 3
Please enter the Value of 1 Element : Apple
Please enter the Value of 2 Element : Banana
Please enter the Value of 3 Element : Orange
Please enter the New Item to append : Kiwi
Original Items are : ['Apple', 'Banana', 'Orange']
New Items are : ['Apple', 'Banana', 'Orange', 'Kiwi']
