Python Program to Append an Item to a List

Write a Python program to append an item to a list. In Python, we have multiple options to append or add an item to a list, and here, we use the append method. The list append method adds a new element to the end of a list.

list.append(item)

numbers = [10, 20, 30, 40, 50]

print("Numeric List Before Appending Item")
print(numbers)

numbers.append(65)

print("Numeric List After Appending First Item")
print(numbers)

value = int(input("Please enter the List Item = "))
numbers.append(value)

print("Numeric List After Appending Second Item")
print(numbers)

Python Program to Append an Item to a List

This python program appends an item to a list using the index function. The list index method adds a list element at the specified index.

list.insert(index, item)

countries = ["India", "USA", "UK", "Italy"]

print("List Before Appending Item")
print(countries)

countries.insert(3, "Japan")
print("\nList After Appending Japan at 3rd Index Position")
print(countries)

countries.insert(0, "China")
print("\nList After Appending China at 0 Index Position")
print(countries)

countries.insert(6, "France")
print("\nList After Appending France at 6 Index Position")
print(countries)

List Before Appending Item
['India', 'USA', 'UK', 'Italy']

List After Appending Japan at 3rd Index Position
['India', 'USA', 'UK', 'Japan', 'Italy']

List After Appending China at 0 Index Position
['China', 'India', 'USA', 'UK', 'Japan', 'Italy']

List After Appending France at 6 Index Position
['China', 'India', 'USA', 'UK', 'Japan', 'Italy', 'France']

This Python example allows entering the list index and the list value and adds that new item using the index method.

numbers = [11, 22, 33, 44, 55, 66]

print("Numeric List Before Inserting Item")
print(numbers)


index = int(input("Please enter Index Position = "))
value = int(input("Please enter the List Value = "))

numbers.insert(index, value)

print("Numeric List After Appending Item")
print(numbers)

Numeric List Before Inserting Item
[11, 22, 33, 44, 55, 66]
Please enter Index Position = 4
Please enter the List Value = 111
Numeric List After Appending Item
[11, 22, 33, 44, 111, 55, 66]

Python program to append an item to a list using extend method

The list extend method adds any iterable such as list, tuple, string, etc to the end of the existing list.

list.extend(iterator)

countries = ["India", "USA", "UK", "Italy"]

print("List Before Appending Item")
print(countries)

tuple1 = ("Japan", "China", "France")
countries.extend(tuple1)
print("\nList After Appending Tuple using extend")
print(countries)

list1 = [19, 17, 39, 55]
countries.extend(list1)
print("\nList After Appending List sing extend")
print(countries)

countries.extend((11.5, 19.2))
print("\nList After Appending 11.5, 19.2 using extend")
print(countries)

List Before Appending Item
['India', 'USA', 'UK', 'Italy']

List After Appending Tuple using extend
['India', 'USA', 'UK', 'Italy', 'Japan', 'China', 'France']

List After Appending List sing extend
['India', 'USA', 'UK', 'Italy', 'Japan', 'China', 'France', 19, 17, 39, 55]

List After Appending 11.5, 19.2 using extend
['India', 'USA', 'UK', 'Italy', 'Japan', 'China', 'France', 19, 17, 39, 55, 11.5, 19.2]
