Understanding the syntax of dictionary

Question

I've tried to run following program
squares = {1: 1, 2: 4, 3: "error", 4: 16,}
squares[8] = 64
squares[3] = 9
print(squares)

In my IDLE I'm getting output : {1: 1, 2: 4, 3: 9, 4: 16, 8: 64}
which makes sense but in your result window, I'm seeing result : {8: 64, 1: 1, 2: 4, 3: 9, 4: 16}
which one is right one ?

Answer 1

Dictionary keys are not ordered( opposite to List). so every time you will get different output unless you force to print one by one using keys.sort().
