msgid "Enum HOWTO"
msgstr ""
msgid ""
"An :class:`Enum` is a set of symbolic names bound to unique values. They "
"are similar to global variables, but they offer a more useful :func:"
"`repr()`, grouping, type-safety, and a few other features."
msgstr ""
msgid ""
"They are most useful when you have a variable that can take one of a limited "
"selection of values. For example, the days of the week::"
msgstr ""
msgid "Or perhaps the RGB primary colors::"
msgstr ""
msgid ""
"As you can see, creating an :class:`Enum` is as simple as writing a class "
"that inherits from :class:`Enum` itself."
msgstr ""
msgid "Case of Enum Members"
msgstr "Wielkość liter literałów wyliczeniowych"
msgid ""
"Because Enums are used to represent constants we recommend using UPPER_CASE "
"names for members, and will be using that style in our examples."
msgstr ""
msgid ""
"Depending on the nature of the enum a member's value may or may not be "
"important, but either way that value can be used to get the corresponding "
"member::"
msgstr ""
msgid ""
"As you can see, the ``repr()`` of a member shows the enum name, the member "
"name, and the value. The ``str()`` of a member shows only the enum name and "
"member name::"
msgstr ""
msgid "The *type* of an enumeration member is the enum it belongs to::"
msgstr ""
msgid "Enum members have an attribute that contains just their :attr:`name`::"
msgstr ""
msgid "Likewise, they have an attribute for their :attr:`value`::"
msgstr ""
msgid ""
"Unlike many languages that treat enumerations solely as name/value pairs, "
"Python Enums can have behavior added. For example, :class:`datetime.date` "
"has two methods for returning the weekday: :meth:`weekday` and :meth:"
"`isoweekday`. The difference is that one of them counts from 0-6 and the "
"other from 1-7. Rather than keep track of that ourselves we can add a method "
"to the :class:`Weekday` enum to extract the day from the :class:`date` "
"instance and return the matching enum member::"
msgstr ""
msgid "The complete :class:`Weekday` enum now looks like this::"
msgstr ""
msgid "Now we can find out what today is! Observe::"
msgstr ""
msgid ""
"Of course, if you're reading this on some other day, you'll see that day "
"instead."
msgstr ""
msgid ""
"This :class:`Weekday` enum is great if our variable only needs one day, but "
"what if we need several? Maybe we're writing a function to plot chores "
"during a week, and don't want to use a :class:`list` -- we could use a "
"different type of :class:`Enum`::"
msgstr ""
msgid ""
"We've changed two things: we're inherited from :class:`Flag`, and the values "
"are all powers of 2."
msgstr ""
msgid ""
"Just like the original :class:`Weekday` enum above, we can have a single "
"selection::"
msgstr ""
msgid ""
"But :class:`Flag` also allows us to combine several members into a single "
"variable::"
msgstr ""
msgid "You can even iterate over a :class:`Flag` variable::"
msgstr ""
msgid "Okay, let's get some chores set up::"
msgstr ""
msgid "And a function to display the chores for a given day::"
msgstr ""
msgid ""
"In cases where the actual values of the members do not matter, you can save "
"yourself some work and use :func:`auto()` for the values::"
msgstr ""
msgid "Programmatic access to enumeration members and their attributes"
msgstr ""
msgid ""
"Sometimes it's useful to access members in enumerations programmatically (i."
"e. situations where ``Color.RED`` won't do because the exact color is not "
"known at program-writing time). ``Enum`` allows such access::"
msgstr ""
msgid "If you want to access enum members by *name*, use item access::"
msgstr ""
msgid "If you have an enum member and need its :attr:`name` or :attr:`value`::"
msgstr ""
msgid "Duplicating enum members and values"
msgstr ""
msgid "Having two enum members with the same name is invalid::"
msgstr ""
msgid ""
"However, an enum member can have other names associated with it. Given two "
"entries ``A`` and ``B`` with the same value (and ``A`` defined first), ``B`` "
"is an alias for the member ``A``. By-value lookup of the value of ``A`` "
"will return the member ``A``. By-name lookup of ``A`` will return the "
"member ``A``. By-name lookup of ``B`` will also return the member ``A``::"
msgstr ""
msgid ""
"Attempting to create a member with the same name as an already defined "
"attribute (another member, a method, etc.) or attempting to create an "
"attribute with the same name as a member is not allowed."
msgstr ""
msgid "Ensuring unique enumeration values"
msgstr ""
msgid ""
"By default, enumerations allow multiple names as aliases for the same value. "
"When this behavior isn't desired, you can use the :func:`unique` decorator::"
msgstr ""
msgid "Using automatic values"
msgstr ""
msgid "If the exact value is unimportant you can use :class:`auto`::"
msgstr ""
msgid ""
"The values are chosen by :func:`_generate_next_value_`, which can be "
"overridden::"
msgstr ""
msgid ""
"The :meth:`_generate_next_value_` method must be defined before any members."
msgstr ""
msgid "Iteration"
msgstr "Iteracja"
msgid "Iterating over the members of an enum does not provide the aliases::"
msgstr ""
msgid ""
"Note that the aliases ``Shape.ALIAS_FOR_SQUARE`` and ``Weekday.WEEKEND`` "
"aren't shown."
msgstr ""
msgid ""
"The special attribute ``__members__`` is a read-only ordered mapping of "
"names to members. It includes all names defined in the enumeration, "
"including the aliases::"
msgstr ""
msgid ""
"The ``__members__`` attribute can be used for detailed programmatic access "
