When am I supposed to use del in python?

Question

So I am curious lets say I have a class as follows

class myClass:
    def __init__(self):
        parts = 1
        to = 2
        a = 3
        whole = 4
           


        

Answer 1

One use is to delete specific keys from a dictionary.

>>>> food = {"apple": True, "banana": False}
>>>> del food['banana']
>>>> import json
>>>> json.dumps(food)
'{"apple": true}'

I use it all the time for cleaning up dictionaries before converting them to JSON.
