#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]
