Associations¶

$ wo '<|"Green" -> 2, "Red" -> 1|>'
<|Green -> 2, Red -> 1|>

$ wo 'myHash = <|"Green" -> 2, "Red" -> 1|>'
<|Green -> 2, Red -> 1|>

Access values in associations¶

$ wo 'myHash = <|"Green" -> 2, "Red" -> 1|>; myHash[["Green"]]'
2

$ wo 'myHash = <|1 -> "Red", 2 -> "Green"|>; myHash[[1]]'
Red

$ wo 'assoc = <|"a" -> True, "b" -> False|>; assoc[["b"]]'
False

$ wo 'myHash = <|"Green" -> 2, "Red" -> 1|>; myHash[["Green"]] = 5; myHash'
<|Green -> 5, Red -> 1|>

$ wo 'myHash = <|"Green" -> 2, "Red" -> 1|>; myHash[["Puce"]] = 3.5; myHash'
<|Green -> 2, Red -> 1, Puce -> 3.5|>
