English:
    1. Define function `cube()`:
       a. takes one argument
       b. returns its argument cubed (raised to the power of 3)
    2. Use `map()` to apply function `cube()` to DATA
    3. Define `result: list[int]` with evaluated result
    4. Run doctests - all must succeed

Polish:
    1. Zdefiniuj funckję `cube()`:
       a. przyjmuje jeden argument
       b. zwraca argument podniesiony do sześcianu (do 3 potęgi)
    2. Użyj `map()` zaaplikować funkcję `cube()` do DATA
    3. Zdefiniuj `result: list[int]` z ewaluaownym wynikiem
    4. Uruchom doctesty - wszystkie muszą się powieść

Hints:
    * map()
    * list()

Tests:
    >>> import sys; sys.tracebacklimit = 0
    >>> from inspect import isfunction

    >>> assert isfunction(cube), \
    'Object `cube` must be a function'
    >>> assert result is not Ellipsis, \
    'Assign result to variable: `result`'
    >>> assert type(result) is list, \
    'Variable `result` has invalid type, should be list'
    >>> assert all(type(x) is int for x in result), \
    'All rows in `result` should be int'

    >>> result
    [0, 1, 8, 27, 64, 125, 216, 343, 512, 729]
