list.insert(index, element)append(): append the object to the end of the list.
insert(): inserts the object before the given index.
extend(): extends the list by appending elements from the iterable.#add item to the beginning of list – at index 0
clouds = [‘Cisco’, ‘AWS’, ‘IBM’]
clouds.insert(0, ‘Google’)
print(clouds)
[‘Google’, ‘Cisco’, ‘AWS’, ‘IBM’]
#add item to the end of list
a.insert(len(a),x) is equivalent to a.append(x)
clouds = [‘Cisco’, ‘AWS’, ‘IBM’]
clouds.insert(len(clouds), ‘Google’)
print(clouds)
[‘Google’, ‘Cisco’, ‘AWS’, ‘IBM’]
#add item to specific index
number_list = [10, 20, 40] # Missing 30.
number_list.insert(2, 30 ) # At index 2 (third), insert 30.
print(number_list) # Prints [10, 20, 30, 40]
number_list.insert(100, 33)
print(number_list) # Prints [10, 20, 30, 40, 33]
number_list.insert(-100, 44)
print(number_list) # Prints [44, 10, 20, 30, 40, 33]# create a list of vowels
vowel = ['a', 'e', 'i', 'u']
# 'o' is inserted at index 3 (4th position)
vowel.insert(3, 'o')
print('List:', vowel)
# Output: List: ['a', 'e', 'i', 'o', 'u']FOMAT: list.insert(index,element)
hey you, I want you to remember that insert function
takes the index as the parameter okay?
Just remember it as "insert" starts with "i" so the first parameter of insert
also starts with i
Sounds crazy but works...have a good day. Dont forget this concept.
# Python program to demonstrate
# Addition of elements in a List
# Creating a List
List = [1,2,3,4]
print("Initial List: ")
print(List)
# Addition of Element at
# specific Position
# (using Insert Method)
List.insert(0, 0)
List.insert(5, 'Softhunt.net')
print("\nList after performing Insert Operation: ")
print(List)
