add :flatten attribute that flatten the nested result list
add :flatten attribute that flatten the result list if it's nested. below is the example.
>>> math.sqrt([1, [2, 3]]) [1, [1.41421, 1.73205]] >>> math.sqrt([1, [2, 3]])]:flatten [1, 1.41421, 1.73205]
:flat attribute was implemented
math.sqrt([1, [2, 3]]):flat [1, 1.41421, 1.73205]
