  8. ======
  9. A built-in type for strings.

  11. Description
  12. -----------
  13. This is the built-in string Variant type (and the one used by GDScript). Strings may contain any number of Unicode characters, and expose methods useful for manipulating and generating strings. Strings are reference-counted and use a copy-on-write approach (every modification to a string returns a new **String**), so passing them around is cheap in resources.
  14. Some string methods have corresponding variations. Variations suffixed with ``n`` (:ref:`countn()<class_String_method_countn>`, :ref:`findn()<class_String_method_findn>`, :ref:`replacen()<class_String_method_replacen>`, etc.) are **case-insensitive** (they make no distinction between uppercase and lowercase letters). Method variations prefixed with ``r`` (:ref:`rfind()<class_String_method_rfind>`, :ref:`rsplit()<class_String_method_rsplit>`, etc.) are reversed, and start from the end of the string, instead of the beginning.
  15. To convert any :ref:`Variant<class_Variant>` to or from a string, see :ref:`@GlobalScope.str()<class_@GlobalScope_method_str>`, :ref:`@GlobalScope.str_to_var()<class_@GlobalScope_method_str_to_var>`, and :ref:`@GlobalScope.var_to_str()<class_@GlobalScope_method_var_to_str>`.
  16. \ **Note:** In a boolean context, a string will evaluate to ``false`` if it is empty (``""``). Otherwise, a string will always evaluate to ``true``.
  17. .. note::
  18. There are notable differences when using this API with C#. See :ref:`doc_c_sharp_differences` for more information.

  394. Performs a case-sensitive comparison to another string. Returns ``-1`` if less than, ``1`` if greater than, or ``0`` if equal.

  503. Formats the string by replacing all occurrences of ``placeholder`` with the elements of ``values``.
  504. \ ``values`` can be a :ref:`Dictionary<class_Dictionary>`, an :ref:`Array<class_Array>`, or an :ref:`Object<class_Object>`. Any underscores in ``placeholder`` will be replaced with the corresponding keys in advance. Array elements use their index as keys.

  506. # Prints "Waiting for Godot is a play by Samuel Beckett, and Godot Engine is named after it."

  509. # Prints "User 42 is Godot."
  510. print("User {id} is {name}.".format({"id": 42, "name": "Godot"}))
  511. Some additional handling is performed when ``values`` is an :ref:`Array<class_Array>`. If ``placeholder`` does not contain an underscore, the elements of the ``values`` array will be used to replace one occurrence of the placeholder in order; If an element of ``values`` is another 2-element array, it'll be interpreted as a key-value pair.
  512. ::
  513. # Prints "User 42 is Godot."
  514. print("User {} is {}.".format([42, "Godot"], "{}"))
  515. print("User {id} is {name}.".format([["id", 42], ["name", "Godot"]]))
  516. When passing an :ref:`Object<class_Object>`, the property names from :ref:`Object.get_property_list()<class_Object_method_get_property_list>` are used as keys.
  517. ::
  518. # Prints "Visible true, position (0, 0)"
  519. var node = Node2D.new()
  520. print("Visible {visible}, position {position}".format(node))
  521. See also the :doc:`GDScript format string <../tutorials/scripting/gdscript/gdscript_format_string>` tutorial.
  522. \ **Note:** Each replacement is done sequentially for each element of ``values``, **not** all at once. This means that if any element is inserted and it contains another placeholder, it may be changed by the next replacement. While this can be very useful, it often causes unexpected results. If not necessary, make sure ``values``'s elements do not contain placeholders.
  523. ::
  524. print("{0} {1}".format(["{1}", "x"])) # Prints "x x"
