I noticed today iterate a dict works also different.
While translating scripts from py2 to py3 this was a thing...
If the keys are integers in py2 they will be sorted.
In py3 the will stay in order as appended to dict.
print {1:"A",0:"B"}
> {0: 'B', 1: 'A'}
vs
print({1:"A",0:"B"})
> {1: 'A', 0: 'B'}
(also it seems print()
is not coloured in snippet)
