A
list is an ordered collection of items.
The items can be approached with their index.
a = [3, 0, 5]
a:list[int] = [3, 0, 5]
A
set is an unordered collection of unique items.
You can assign the same item as many times as you want without error.
It will appear just once in the set.
a = {3, 0, 5}
a:set[int] = {3, 0, 5}
A
dictionary is an unordered collection of key-value pairs.
a = {3: 'E'}
a:dict[int, str] = {3: 'E', 0: 'G', 5: 'S'}
The
:list[] etc. are just datatype suggestions for the IDE.
They don't mean anything to the actual program, and you can still
assign whatever you want to the variable.
