Adding items or elements to the list

 Adding items or elements to the list :

append() : add new item at the end 

insert() : add new item at specific place in the list 

extend() : add the multiple items at the end of the list

Using append()

my_list=['a', 'b']

my_list.append('c')

print(my_list)

Explanation

• my_list = ['a', 'b']: In this line of code, we create a list named my_list with items: 'a' and 'b'.

• my_list. append ('c'): In this code line, we use the append method to add a new item 'c' at the end of my_list.

• print (my_list): This line prints the list.

Output :

['a', 'b', 'c']

Using insert()

After running the code, the output displayed on the console will be ['a',

'b', 'c']. Note that 'b' is now at index 1 in the list and right between 'a'

and 'c'. The list item 'c' which was at index 1 previously now has index

2.

my_list = ['a', 'c']

my_list.insert(1,'b')

print(my_list)

Output:

['a', 'b', 'c']

Out of range

my_list = ['a', 'bʼ]

my_list.insert(5,'c')

print(my_list)

Output :

['a', 'b', 'c']

• my_list =['a', 'b']: Here, we're creating a list named my_list with two elements: 'a' and 'b'.

• my_list. insert (5, 'c'): We're inserting the element 'c' at index 5, which is beyond length of the list.

• print (my_list): This prints out the updated list.

extend()

my_list = ['a', 'b']

my_list.extend(['c', 'd'])

print(my_list)

• my_list = ['a', 'b']: We make a list named my_list with items 'a' and 'b'.

• my_list. extend (['c', 'd']): In this code line, we use the extend method to add multiple items ('c' and 'd') to the end of the list.

• print (my_list): This line prints the updated list.

Output :

['a', 'b', 'c', 'd']
