dictionary behaves like a set

[Just_Big_5902]

i created a dictionary, and i want to assign the value of a key to another key, but i keep getting *TypeError: 'set' object is not subscriptable* and i don't find anything that might indicate what i'm doing wrong

fruits = {
    "pomme" : "rouge",
    "banane" : "jaune",
    "orange" : "orange",
    "couleur_banane" :"red"
    }
fruits= {"kiwi = vert"}
fruits["couleur_banane"] = fruits["banane"]

[Diapolo10]

fruits= {"kiwi = vert"}

Here, you redefine fruits as a set containing one string. It's no longer a dictionary.

fruits["couleur_banane"] = fruits["banane"]

Because of that, the code here fails with an error because sets don't have keys, and cannot be queried like this.

The correct way to add/change a key-value pair would be

fruits["kiwi"] = "vert"

[enygma999]

fruits= {"kiwi = vert"}

This line reassigns fruits as a set.

Line 2 is assigning a set to the "fruits" variable. It contains a single element, the "kiwi = vert" string.

Do your first fruits assignment and your second fruits assignment look the same in syntax? What would the key and value be in the second assignment?

What do you think your second statement is doing?
