Creating a self-numbering ranking list

Question

Can someone offer a solution to this problem? Say I a ranked list:

5. Pineapple
4. Peach
3. Kiwi
2. Apple
1. Banana

I then add a new entry to the ranking:

5. Pineapple
4. Peach
#. Plum <--new text
3, Kiwi
2. Apple
1. Banana

Can I set up the list to automatically reorder as follows?

6. Pineapple
5. Peach
4. Plum
3, Kiwi
2. Apple
1. Banana

Thanks!

Answer 1

use can use the Slicing indexing in Python to split and append a new element and then join it to create a new list with the new element having a certain index.

Here is the code and I want you to learn from it not just expect answers from the community.

Savager

you should try list.insert()

or you can use OOP for more advanced list operations:

Answer 3

#Savager copy-paste this:

#class inherit from list
class MyList(list):
def __init__(self, li):
super().__init__(v for v in li)

#custom __str__method
def __str__(self):
s = ""
for i, v in enumerate(self):
s+=f'{len(self)-i}. {v}\n'
return s

#custom insert method
def insert(self, i, v):
super().insert(len(self)-i, v)

## TEST ##
fruits = MyList(['Pineapple', 'Peach'])
#custom __str__method
print(fruits)
#built-in list methods
fruits.append('Kiwi')
fruits.extend(['Apple', 'Banana'])
print(fruits)
#custom insert method
fruits.insert(3, 'Plum')
print(fruits)
