* Assignment: Conditional Expression IPv4/IPv6
* Required: yes
* Complexity: easy
* Lines of code: 1 lines
* Time: 3 min

English:
    1. To `result: bool` assign whether `IP_ADDRESS` is IPv4 or IPv6 protocol:
       a. `IPv4` if dot `.` is in the IP address
       b. `IPv6` if dot `.` is not in the IP address
    2. Non-functional requirements:
       a. Use one line `if`
    3. Run doctests - all must succeed

Polish:
    1. Do `result: bool` przypisz czy `IP_ADDRESS` jest protokołu IPv4 czy IPv6:
       a. `IPv4` jeżeli jest kropka `.` w adresie IP
       b. `IPv6` jeżeli kropki nie ma
    2. Wymagania niefunkcjonalne:
       a. Wykorzystaj jednolinikowego `if`
    3. Uruchom doctesty - wszystkie muszą się powieść

Hints:
    * `in`

Tests:
    >>> import sys; sys.tracebacklimit = 0

    >>> assert result is not Ellipsis, \
    'Assign your result to variable `result`'

    >>> assert type(result) is str, \
    'Variable `result` has invalid type, should be str'

    >>> assert result in ('IPv4', 'IPv6'), \
    'Variable `result` must be either `IPv4` or `IPv6`'
