Builtin functions and exceptions
================================

.. warning::

    These builtins are inherited from MicroPython and may not work in CircuitPython
    as documented or at all! If work differently from CPython, then their behavior
    may change.

All builtin functions and exceptions are described here. They are also
available via ``builtins`` module.

Functions and types
-------------------

.. function:: abs()

.. function:: all()

.. function:: any()

.. function:: bin()

.. class:: bool()

.. class:: bytearray()

.. class:: bytes()

    |see_cpython| `bytes`.

.. function:: callable()

.. function:: chr()

.. function:: classmethod()

.. function:: compile()

.. class:: complex()

.. function:: delattr(obj, name)

   The argument *name* should be a string, and this function deletes the named
   attribute from the object given by *obj*.

.. class:: dict()

.. function:: dir()

.. function:: divmod()

.. function:: enumerate()

.. function:: eval()

.. function:: exec()

.. function:: filter()

.. class:: float()

.. class:: frozenset()

.. function:: getattr()

.. function:: globals()

.. function:: hasattr()

.. function:: hash()

.. function:: hex()

.. function:: id()

.. function:: input()

.. class:: int()

   .. classmethod:: from_bytes(bytes, byteorder)

      In MicroPython, `byteorder` parameter must be positional (this is
      compatible with CPython).

   .. method:: to_bytes(size, byteorder)

      In MicroPython, `byteorder` parameter must be positional (this is
      compatible with CPython).

.. function:: isinstance()

.. function:: issubclass()

.. function:: iter()

.. function:: len()

.. class:: list()

.. function:: locals()

.. function:: map()

.. function:: max()

.. class:: memoryview()

.. function:: min()

.. function:: next()

.. class:: object()

.. function:: oct()

.. function:: open()

.. function:: ord()

.. function:: pow()

.. function:: print()

.. function:: property()

.. function:: range()

.. function:: repr()

.. function:: reversed()

.. function:: round()

.. class:: set()

.. function:: setattr()

.. class:: slice()

   The *slice* builtin is the type that slice objects have.

.. function:: sorted()

.. function:: staticmethod()

.. class:: str()

.. function:: sum()

.. function:: super()

.. class:: tuple()

.. function:: type()

.. function:: zip()


Exceptions
----------

.. exception:: AssertionError

.. exception:: AttributeError

.. exception:: Exception

.. exception:: ImportError

.. exception:: IndexError

.. exception:: KeyboardInterrupt

.. exception:: KeyError

.. exception:: MemoryError

.. exception:: NameError

.. exception:: NotImplementedError

.. exception:: OSError

    |see_cpython| `OSError`. MicroPython doesn't implement ``errno``
    attribute, instead use the standard way to access exception arguments:
    ``exc.args[0]``.

.. exception:: RuntimeError

.. exception:: ReloadException

   `ReloadException` is used internally to deal with soft restarts.

.. exception:: StopIteration

.. exception:: SyntaxError

.. exception:: SystemExit

    |see_cpython| :py:class:`python:SystemExit`.

.. exception:: TypeError

    |see_cpython| :py:class:`python:TypeError`.

.. exception:: ValueError

.. exception:: ZeroDivisionError
