I believe this was mentioned in 9. Python lists and dictionaries.
To do so, you can simply use the
list_name.insert(index, newly_added) function.
For example, you start out with a list
animals = ["ant", "bat", "bird"] and you want to insert
"dog" right behind
"ant". To do so, you just have to do
animals.insert(1, "dog"), and if you print the list again afterwards, you will realise that
"dog" has been added in right where you want while
"bird" have shifted back by one index correspondingly. (Remember that you start counting indexes from 0!)
Hope this helps
