set() in Python

I have used the set() function but I am confused.

x = set("car")
print(x)

Why does this code output: "a", "c", "r" and not "car"? Thanks for your answers.

>Solution :

It’s because of the main properties of set in Python.

• They can’t contain duplicates
• They’re unordered

So things like this one just happen.

>>> set("car")
{'a', 'r', 'c'}

I suggest you to read this useful documentation about Python’s set.

• Python – Set
• Programiz – Python’s Set
• W3Schools – Python’s Set

If you really want an ordered set, there’s something that can be useful to you.

• OrderedSet
